Very informative video. There's a distinct lack of science of results on these boxes so, it's great to see a before and after dyno run, much like you would after an actual remap.

how has this not got more attention, well made video, thanks for doing this man!

Initially when I got my RC, i didn't feel i noticed too much increase, it took my a while to notice. I contacted RC customer support via email and explained that I felt it was not giving me the power i expected. They sent me an update to install and i have to say i really do notice when it is turned on. On highest setting it always feels like the turbo is raring to kick in. I usually drive with it set to 4. It definitely picks up quicker than without it. I've had mine over 2 years now and hate driving with it off. Expensive, yes. But so glad i bought one.

I had the basic racechip on my A200d with the 2.2d engine. It made a real nice difference. The jump in torque made a big difference to the way it drove in normal traffic. I did over 100,000 miles in that car and it did not effect mpg in any way. Averaged 68mpg over 100,000 miles.

Fitted one to a turbo diesel i30 Hyundai. Definitely made a reasonable difference. The increased mpg on the trip computer was way out but measuring the mpg myself it gained 1 or 2 mpg which isn't much but considering the extra power it was a win win. Ran it for 50k miles and it never caused any issues.

Ive had a Racechip on my 2014 Audi A6 TDI. Purchased in 2018, (now 2023). While I do notice a difference it's not the same as a tune. No problems with the RC and I purchased another for a friends vehicle. Again, he enjoyed the performance gains. System spoofs the sensors and offers more trq than HP. Easy to install and remove. Overall OK but not what is claimed on HP at all. Also, at the higher RPM's I also didn't notice any improvement.

I installed on my Mercedes CLS550 about a year ago. More power, better response and very reliable. I do not know how much more power, but the Mustang and Hemi people are trying to catch me.

One thing to consider... as a race chip owner on a Panamera Turbo, is the race chip has a bit of a learning mode. It obtains its maximum improvements after a period of time, up to 200 miles clocked after installation.

Thank you so much for this video bud, I have a Gle 450 coupe and I was thinking of installing Racechip for me from 275kw and 520 torque stock they say it will jump to 331kw and 620 torque but after this video I highly doubt I’ll ever get close to those gains maybe 10-15kw and 20-40 torque more but it’s certainly not worth the money they wanna charge me. Which is 9500 South African rands.

I've installed Race Chip on many of my own vehicles and all have worked very well. My MK8 GTI picked up 4 mph at our local 1/8th mile drag strip, only mod was the Race Chip. My Wife's Cayman S picked up almost 50 whp and 60 ft/lbs on the dyno with only the Race Chip as well.

I have a Racechip GTS for my 2020 1.5 ecoboost. Which stock is only 182 hp but after installing the Racechip and a cold air intake it pushes 247 hp. Definitely worth it.

my Sportage CRDi 184 bhp becomes a crazy toy with the raceship on!!! Amazing difference, More response and more power, better gas mileage. I LOV IT ! Same on my Montero Sport before . Big difference . And with only basic raceship.

I wonder if additional torque and HP achieve by combining Racechip & Revo infinity in a parallel function? I had conducted numerous public tests installation and test in the past. I persuaded my buddy to partake in competition to prove that the gadget can actually perform and function and also are meeting International Stds & expectation. Without testing, it is hard for most people to believe it's actually works wonder for the installed engine. I am glad he took my advice in partaking competition. It claims the Golden & Best Product Awards of MTE and The Best Innovation Awards Issues by Association of British inventors and innovators. I hope the awareness of this gadget can be widely spread in the movement combating climate change. It's an opportunity to cooperate and an individual has the opportunity to partake in combating climate change. Thks

For the people who like to know: It's interrupts the voltage signal coming from the common rail pressure sensor and forwards a higher or lower value depending on the chosen setting. The ECU bumps up the demand of the pump a.k.a. pressure because it's sees a lower value from the sensor. Now because the pressure is slightly higher and the duration of the injection is still original ECU, the end result is still a higher volume being injected in said duration of injection time resulting in a higher bang. And since cars are always tuned from factory for balanced power and pollution setting. You can get away with adding that little bit of fuel without getting in to trouble.

Interesting video Gavin. I have a tune box on my Velar and it should take bhp from 180 to 240. It’s certainly much more rapid with TDItune box turned on.

@zeroyon Where did you bought this front Lip/Splitter? I am looking for this one in Europe but cant find one.

Great video I bought a race chip for a 2018 megane diesel I know this wasn't a lightning fast car but the race chip produced no difference whatsoever I did every they told me to and they even did an upgrade but still nothing I returned it lossed around £50 got it remapped buy superchips and it was a different car this is obviously my experience ......

My Racechip made a heap more power yet it took a bit of ECU learning. I slowly turned the setting up each day as advised. On the final day I was on setting 6 and my Kia Cerato GT was flying, advertised 40+kw gain. I pull away rapidly from MK6 GTI DSG and have hit high 5 seconds to 62MPH. Definitely recommend but u must slowly turn them up so your ECU can adjust timing tables etc.

The area under the curve is significantly better. Peak gains are cool for forum bragging rights, but actually driving your car takes place in the low and mid range most of the time. Seems like it’s worth it.

Very good video thanks. I have an e 350 w212. 302 hp. Considering ecu remap. Most informative thanks

thanks for honest results. you gain 7 HP but you cant notice it when driving

Hey man, can you make a video on the visual mods of your car. I reallliked it.

Would this cause any parts to wear quicker?

I have contacted the Company twice now for their Dyno. Nos. for an MBZ 5.5M 273 V8 Litre ( standard 382 HP 391 lbs. torque ) of course I have received no reply because their advertising claims are simply for suckers . An excellent video showing the truth . Thank you .

Initially made aware of chipping many years ago when a work colleague had his 1.8 Audi tt remapped or whatever. It was noticeable and made it more beefed up but about 6 months later something went in the engine and cost him thousands to rectify. Guess im just a bit wary of doing something to an expensive car that would need declaring to insurance company and could potentially cause unknown issues. Nice presentation 👍

I have been driving an Audi A4 with a race chip for 2 years. I don't know what dyno no. would be, but it is much faster than it was without the chip. I have also been looking at what RC can do with other similar engines.. I saw that a VW GTI gets more gains than a Golf R would with a race chip. It makes sense that if an engine is already turn to high output, the gain from RC will be less that an engine that is less tuned. I am sure I will put a Race Chip in very turbo car that I am going to get.

dont they have learning phases? Mine didnt impress me fully until after 2 weeks

Gotta love smaller KZfaqrs doing things the right way, and proving these things with legitimate results with a dyno

I used to have Tdi tuning bix on my fird transit Custom van, when it was brand new, 3 years later on a way home engine made horrible noises so I removed the box and opted for proper remap, and what a difference it made, day and night, as you stated it does a tittle bit but no where near to what they claim at least on diesel vehicles, so from my experience don’t waist your money on these boxes but go for remap.

Awesome! Really interesting! Thanks for sharing!

Thanks, this confirms my decision to go for a proper and safe stage 1 tune which also would cost me just a few hundred quid

When we dyno piggybacks, we notice each subsequent run the car bleeds off any additional power until it is back at stock levels. You get increased boost, but we always see an accompanying closure of throttle, pulling timing, dumping fuel, etc.

Should i bother with my 1.6l lancer ex?

Does anybody know if this can work with a 2008 Mercedes Benz CLS550 (5.5 L V8 ) ?

If you get an engine mgmt light on as a result of using one of these. Let’s say you have it on too high a setting. Can you just remove it and the EML goes away? Or do you need to have other tools to fix it? Concerned about getting one, having issues and then having to pay more money to fix. Thanks for the informative video.

They work fine, though I'd go for the £139 one, seem to give a good dollop of torque just where you need and use it most, they improve as the ECU learns it If you think it's placebo try taking it off, you miss it when it's gone big time. I've had four....

Go to Celtic Tuning. My A200d 2020 plate. Stage 2 remap. £400 230 bhp and 360 lbs ft torque. 0-60 mph in 4.9 secs. No hardware. Just remap! 60mpg avg driving.

Can you get these for petrol engines, if so, have any of those been tested?

I've myself got a Mercedes A200 W177 model with 163bhp, I've got a race chip in mine (quoted 201bhp), and it really does make it feel lightning quick, I actually believe the quoted power too, I measured a 6.9 second 0-60 with it on, and a 7.9 second with it off. Also the feel of the power in 2nd gear really throws you back in your seat unlike when its turned off, and the extra power in 3rd/4th is very noticeable.

Who cares if it does what it says, importantly - does it do it safely? Do they only tell the ECU that it's cold without telling the car anything else, (assuming there are any other parameters that the ECU needs to consider)?

im thinking about getting one for my a180 and im just wondering if they’re definitely safe to use? and are they easy to install?

Ty for this

Hi, I brought a cheap golf 5 tdi gt, running problems, turned out a chip box had been plugged in, 🔌locked the ecu, I removed it and it was fine,

Just to double check, on the RC App, you did not select sport mode as the setting to test on the Dyno... Or did you and it wasnt so clear there is a HP difference?

I got a brand new company car on order VW mk 8 Golf GTD and interested in a tuning box. The only thing that worries me is around getting caught with one by dealer when goes in for a service and potentially insurance consequences because I intend to say nothing to anyone about it. The main concern for me is how easy it is to get caught with a tuning box?

How's it been holding up?

CIAO, lo hai provato in diverse configurazioni di potenza? per intenderci, da 1 a 6 ? grazie

Does this void your warranty

Guys you better get this chip than the remap. Remap burns your turbo in time frame of 6 months to a year and your car will need be repaired. This chip is safe and you can enjoy the difference without stress.

I had a DTUK tuning box on my Audi A5 tdi - it made huge difference and economy was unbelievable. Lovely Merc btw.

hi i wanted to asks an interesting question. so i own a 1.5t mini cooper with stage 1 remap @179hp & 240NM. do you reckon its safe for me to install the lowest version of RaceChip since its going to give me around 20hp which i know is still safe for this specific engine.

Like Darkside developments tested. They don't hit the advertised results. I have a custom remap and our 220 CDI did 197hp, coming from 174hp stock. From 413nm to 505nm

Looks like you got about 20 more horsepower in the low to mid rpm range. That is significant!

Great video. Is there a a different 3rd party app that you can use to measure these figures? The app you used is from the same manufacturer, which of course, biases the results.

Thank you! Very helpful 👍🏻

it does do something, i've had mine for two years now on my 1.6 Jetta TDI when i turn it off the car doesn't feel as lively and responsive

I installed one on my VRS diesel. Made no difference except the MPG calculator was WAY off. After before and after Dyno run, i got my money back and had to then get a remap from a professional company. Do not waste your time with Racechip

Can anyone tell me if it's possible to combine this race chip with a car that already has a stage 1, my fiat bravo 1.6 jtd is 90hp stock, and now at 130hp with stage 1. Can i still use this race chip?

I guess they were basing the gains on stock, so add 20 plus hp if the merc was running stock

Nice car . 👍👍

Don’t you have to let the ecu get used to the chip? Like run it for a few miles ?

I got one on my Civic 9 1.6 diesel. I observed a gain in torque, but not in power. The drive is better for acceleration, and mileage is better (4l /100 km on road at speed of 100 km/h, 5.5 l/100 to 6l/100 km at speed 135 km/h on highway with 4 persons and fully luggage load)

I have a 2012 e70 35d...It's fine as is but what do you recommend???

Been 5 years and I still luv my RaceChip on a Merc C250.

Just look at Darkside Developments testing of tuning boxes especially Race Chip !

s , rs or gts black ?

Racechip doesn't make any guarantees or promises on Horse power. They say up to Xxxx HP. The amount of cold air the engines can get. How restrictive the exhaust is, etc make a huge difference. To get towards the higher end of the potential power gains from a race chip you need to get rid of your Cats, improve the volume of cold air to the engine. Change the injectors, change the cam, Change the turbos, change the exhaust. Now dyno it before the chip and after the chip and you will likely see numbers closer to the up to HP ratings.

Racechip do say to run the car for a week before using the most powerful map to allow the chip to learn.

Very informative, obviously unbiased video, thank you. You forgot to talk about your personal opinion. They lied we can see that, but what was you estimation was it worth it ? The power increase is not great, but the torque increase looks nice, how did you feel that in the car ? Would you buy this thing again ? Or is it "not recommended" ?

Why do they charge $200+ for app control when the app is free ???

50nm gain under the graph is very meaningful to be honest, shame it didnt raise the peak HP so much though.

For £450, I got a custom tune for my Audi diesel - dyno before and after confirmed expected power and torque gains.

Did you guys calculate after the drivetrain loss ? also seems like Benz is copy Bmw underrated their power rate , interesting 🤔

Would it not be better to get a proper stage 1 remap bespoke to your car ? About the same price.

These were all tested by Darkside Developments on their dyno. Findings were they're pretty much all crap and don't live up to expectations. Get a proper base map installed and calibrate it from there with someone who knows what they're doing. People in comments saying it makes a difference, loads more power, feels like its 210bhp. All largely placebo unless you put it on a dyno to prove the results.

So nothing near its cost outlay.. So a faulse performance product sales lie. Thanks for the great video!!

You got to adjust it ^^

Needs to be checked against a remap eg Celtic tuning to confirm value and performance gains over standard

I know this mod works and makes a big difference. Run your test stock vs sport mode on the racechip.

So these chips give it a decent torque boost, got it

I had one of these on an Audi A6 2.7tdi. I went in with my eyes open, I kinda expected it to do very little, as they work by basically putting a resister between the fuel rail and the ecu to manipulate the sensor reading. This ties in pretty much exactly with my own “butt dyno” findings. Race chip quoted an increase from 177bhp to 220, which is total rubbish, but it did pull noticeably harder in the mid range. I guessed it increased the power by about 10bhp, and the mid range by a bit more than that. Basically, do they work? - sort of. Will you get a noticeable increase in power? - Power, probably not, mid range grunt, noticeable but not huge increase. Is the quoted increase total garbage? - absolutely. I think they simply quote the increase you typically get from a remap ( you know, one that directly effects turbo pressures..), and say that it what it will do… Is it a con? - yeah a little bit. They do work…ish, but I wouldn’t buy one again unless it was VERY cheap, and on a very cheap car it didn’t care much for. It could be “worth it” on a crappy golf diesel for the extra mid range, but I’m pretty much every other situation, I’d get a remap instead. I also wouldn’t touch one on a petrol motor, it’s just asking for trouble.

The only way RaceChip can claim the number they claim with a straight face is by comparing the maximum delta between the before and after dyno curves. That, of course, is far different than comparing optimum highest peak hp, before and after. I got a RC for my car, and I'm glad I did not pay MSRP. Got it used for less than 1/2 and still think I overpaid. I felt I got more out of my AccessPort w/TCM for my Nissan GTR for $1100, than this RC for my BMW for $300!!! HP increase was only 60 (advertised 140). I recognize that it is an unfair comparison since the AP will allow you to run e85, bigger injectors, fuel pumps, air intake, etc. But at least you can mod your car to your heart's content.

Much better to get a remap.

I designed one for the first gen Mazda6S. It added 17whp and I think 12lbft. Not a ton, but it wasnt a powerful engine to begin with. They do work, but they have to be set up right and are nowhere near as good as a genuine tune set up for your particular car. That said, I have a dinan in my c300 cuz idc about hardcore power anymore. It's easier and less of a risk.

Any suggestions how can unplug my tuning chip on my car ?

Racechips work clk220cdi night and day mpg more than 30% increase

what front splitter is that mate?

Anybody heard of Evolv Performance Chips?

no matter the car you have and what figures the car maker states the numbers will always be different from another of the same car there is variables like how much friction there is how much flow of air and exhaust there is and many more things

no fan and capto closed? well done, very serious

Can they cause any damage over time?

Do these work if you already have a stage1 Economy remap?

You want to try a dtuk trust me makes a big difference

Need a racechip in my camaro

The box claim is compared to fabric stock claim I guess so then its not to bad.

There's things like extreme fuel rail pressures that others have found

Tbh it sounds, to me, your merc allready had a little optimization in the past. Maybe a little higher temperature from the diesel burning elements and a bit more air? Because if it truly had stock figures (on paper) then the end results with the racechip would be completely accurate... So to me it does work. Allright these engines do always perform a little better with the right fuel and oils. But not this much right? Especially torquewise. But I could be completely wrong.

Finally: it is reported that the RC merely increases the fuel rail pressure - sometimes to dangerous levels!

half peoples say its good and other half its not good, most for those with bigger mileage are not so good

What racechip was this?
