I've seen a bunch of comments regarding "you have to drive the car after the tune to bring the correction factors back up." We did that, you just didn't see it on the video. The instructions state that you can drive it 50 miles OR do repeated 4th gear pulls. We did over 10 pulls and then a cool down before we started logging the new numbers.

I absolutely LOVE the ISF. To me it’s basically an M3 with a Mustang GT engine (except IT’s Lexus reliability and refinement). It’s a beautiful car.

I recently got the RR Tune, intake and elbow. Tuned for primary cats removed. Great upgrade. 7200 redline is awesome and the tune takes the engine to the next level of sport.

this is a great video! perfect eval of this product. exactly what ppl would look for if considering buying the RR tune

i could be wrong but it seems that they didnt use paddles to shift so it might not have reached 7200rpm

4:48 gotta love the startup 👍🏾

Another great video! I'm about to buy an RR Racing tune for my 2010 IS350 Sport, it will basically move redline to 7200 RPM giving me an additional 15 to 20 whp. I'm currently at around 287 whp right now. I don't really need more power, I personally think what I have is sufficient, but being able to move redline to 7200 RPM for some additional power when I need it is awesome. Keep the video's coming!

There’s one error in this. When you re-flash your ECU all of your ignition and knock correction learn value tables reset back to 15 you need to drive the car around for a while And let it learn how far it can advance the timing before detecting knock.

I just bought the tune 2 weeks ago and I got to say its worth it. Feels like a whole new different car in sport manual mode. felt a dramatic increase in the low and mid range power and shifting is more aggressive in first and second gear. Took 2 weeks for my KCLV to reach 21 and that driving alot more then 50 miles. At first the car felt slow.

Good comparison. Thanks for that👍

Hi from Australia, My ISF has headers and Joe Z K&N panel filter. I am uploading the tune on Saturday and will do a few pulls on the dyno as per instructions.

The pulls are to raise the KLVC. Then you will see gains. The tune can optimized for headers, intake and catbck.

Great video sir, I have the RR intake, ppe headers, RR exhaust and flash and it’s worth every penny! Don’t install the engine mounts though unless you want your car to shake and rattle like a old beat up Honda. PS what rear trunk spoiler is that?

Love the induction noise

I own a 2010 and wouldn't trade it for anything else. Would definitely get the tune. Hands down a fun and badass car no one expects on the road! Nice vid btw 👍

The tune works especially the mid-range is improved. I have an FBO ISF and the dyno will never show the potential of the ISF at real road speeds. Any Dyno that I've seen or been at doesn't replicate the correct and real-world air flow at highway speeds where the computer makes adjustments through the MAF sensor on the ISF. The ISF is super finicky with air intake temps and therefore shows its full potential on the road where cooler temps are recognized through the MAF sensor and therefore you get the proper adjustments in your timing curve from the tune.

Drive the car aggressively for a bit, you have to get KCLV up to get a lil more power. But like everyone said, the tune really works if you get headers also

My IS350 made 15whp and 15wtq gain just by replacing the secondary cats with test pipes. Dunno if you’ll get that boost on your ISF but def worth considering too.

Great videos as always... but i was surprised the hood was not open so the car will get heat up faster and you didnt mention which gear you have run ( usually 6th) ... as the say with I/H/E it will be worth it as FBO tune 400+ beast

also, what roads do you hit for driving? I just hit a bunch of backroads down off the AA highway in NKY on Saturday and they were incredible. My dad has an s2k so we took that out. I have a 2018 accord 2.0t MT

Are you getting those Nike signature headlights for the ISF

Thanks for posting ..I know this older but is there a way to remove the tune back to stock? Also have you compared the tune to a pedal commander ? They basically do the same thing without a ECU mod. Is 6-8 wheel HP worth 2500$ your tune and cat back? I’m asking because I don’t know if it’s worth rR racing tune price on my 08 ISF

Rr racing is one of the best when it is about to tune lexus 🥰🥰

Fan of your channel because I had an 08 and currently a 12 ISF, but I think this is the first video that should have been done a little better. The RR Racing tune recommends you to drive 50+ miles or do steady pulls to bring the KCLV back up and for the computer to learn and adapt. Normal KCLV on a well maintained ISF is 21-25, higher with a little bit of octane booster or gallon of E85. When you reset the battery or rewrite the software, the KCLV usually drops to 15 and has to rise from there. The higher the KCLV the more power you have, and it's also a good indicator to see on a higher mile ISF if the car is having any other issues such as dirty MAF, clogged air filter, old plugs, bad fuel, etc. I had the same tune on my 08 ISF with just a borla, and on my 12 with PPE headers and Borla and current XForce Varex exhaust. I never dyno'd, but roll racing or passing on the highway, the tune is a noticeable improvement with no downsides.

I’m in between one of these or an f30 335i, I know you had both. Which would you pick?

Great video. I have similar mods on my 2013 ISF except for HPS elbow and AFE dry filter. I recently started blending E85 (for an E30-35 mix) to raise KCLV. Any plans to blend E85 and perhaps re-dyno?

Did you guys run the car for 50 miles? Rr racing says you need to run the car to see the final restuslts

Just found out that you were in Cincy... thats so awesome. Cincy boys all day

Not sure if you have yet, but PPE or SIKKI headers will give a huge bump with the tune and the exhaust you have. Also look at the K&N cold air kit

8hp for $650 nice job RR. If you want a real tune for the 2UR-GSE get the OVTUNE, did on my RCF and it's night/day difference.

What happens if your car is AWD? There's no rollers for the front wheels on this dyno

You gained 8-9 peak whp but what did you gain in the mid range, middle of the powerband. The peak is not relevant since you'll hardly peak and even so be there briefly. Did you gain more in the midrange. I have to say it sounds awesome.

I would like to see you test the software with an actual cold air intake (K&N)

Will an iDrive be reccomended for this car?

nice! im boutta do 0 mods dyno run and then with all bolt ons dyno run.

What cars and coffees do you go to? I'm in Newport

Can you find an is200t to do this to, can’t find any dynos on KZfaq

It takes some time for the ecu to relearn and advance the timing up to its maximum. I dont think 1 pull would show the best results! I bet after 2 or 3 pulls you would see it increase

I'm in the greater Cincinnati area. nice car man I have a 06 is250

Looking at that Dyno sheet, it looks like the guy on the dyno didn’t rev it to 7200rpm

Best hp gain on a isf is defintly the headrs you should do it

you planning on the PPE headers or you gonna go straight super charger on this ISF? what's your end goal with it? staying NA or forced induction..?

It's a minimal gain but you'd expect the f to be pretty well tuned stock & being NA as said there's not going to be a lot in it, makes me wonder whether to just leave it stock

What exhaust is that

I get rocks thrown at me for saying that their tune is really just a little adjustment to mixture and timing. Yet in every dyno video its proven that the changes are minimal.

You have the frrsh tail lights, now you just need the replacement headlights and this would be the cleanest isf

One thing I don't get it, is they rework the ecu with no turbo or supercharger..??? I'm no mechanic but, this things don't work if you don't have force induction....

I want a 2010 ISF so bad! They aren’t that available and that causes a ridiculous asking price. Are there any comparable, affordable Lexus’?

Good content, man; however, this one is a bummer... 9hp for $600? What about torque? Seems like no gain as you had more variance in heat soak at first run.

Toyota is backwards when it comes to the way it controls the ecu timing, so the knock correction value (kclv) will be at 0 when you first reset the ecu. To get it to the highest point you need to do at least a few 5th and 6th gear low rpm full throttle runs and the ecu will start correcting and you will gain a ton of power. I also recommend a blend of e30 in it so the ecu will have even more breathing room.

Did I miss you showing the AF ratios post tune?

So it’s only worth getting the tune if you plan on getting headers along with it?

havent seen you in cincy. I have a black 08 F. have to get together for a cruise soon!

I have a stock 08 gs 460 is this worth buying? Along with isf tcu?

Did they dyno in paddle shift red line to 7200 rpm? RR Racing Tune will gain more hp with PPE header. 😎

Is that a Wald spoiler? It looks a little different than what I remember... I like it. Can you post a link for it? I want :)

If I have ppe headers, rr cold air intake, and exhaust how much horsepower do you think I could expect to gain with this tune?

I thought they made a new ISF for a sec... those taillights make such a huge difference

Did you have any issues with check engine lights? If so was RR- Racing able to work with you to iron out the issue?

EatSleepDrive do you think it's a good idea to have the car tune and 2nd did have any issues after the tune ?

Are those OEM IS F wheels? Would love to put those on my IS350...

Throw. Sikky headers on then Dyno it Isf are great stock

Anyone know where to get pulleys for a IS 250?

Thinking of buying a ISF but I'm afraid of the valley plate leak. Any things to look out for before buying?

Ive got an IS500, and honestly the things got tons of power, but i am still a bit interested in this tune, im assuming it would void the warranty though, does anyone know this for sure?

Didn’t know all dynos put out different numbers thought it would have a standard

Can the tuning device order an uber eats? Or, airbnb?

What year is this particular IS F?

Does this ruin the engine or decreases the reliability of the car?

You need an inbox air filter like k&n to gain more bhp

That seem really rich

I want that on my ls600

Your F makes pretty low power for what’s done to it. Stock should have been around 350 wheel. An exhaust should have bumped it to 360+ and especially adding the tune, you should have been around the 380 mark. Either their dyno isn’t accurate, something is going on with your car, or the ECU hasn’t had any time to fully relearn and adjust to what’s been added such as exhaust and tune and that’s why everyone keeps saying about the added pulls. Gutted headers and some intake stuff and you’d be at 400. A little below or a little above.

Old intro is best intro

what rim is that

Why did you sell your Bmw

Headers please

What’s the throttle response like? Is it more responsive or the same as stock?

this is kinda weird, you said your isf does 350hp stock, shouldnt the isf do 420hp stock?

I recently got the RR tune done with only the intake elbow and oil separator the only mods on the car. Stock the car was super rich up high and after the tune more so. Power was up only 6-7 hp. I have to do more investigation as to why it is so rich. Exhaust and headers being done in the next month or so.

Trick is, get your mods done then flash it for best over all benefit.

How come they didnt dyno with the hood open?

Torque is all that matters. And lol @ the price of that

What’s the point of blowing fans with the hood closed?

Why didn’t they raise your RPM limiter to 7,200 or 7,400 like everyone else with the tune? I have RRs full bolt on kit (intake, headers, exhaust, tune). If you want power you have to get PPE headers. You’ll be around 400-420whp then. The intake, exhaust or tune isn’t where this car makes / loses power it’s the headers

Hello, The Lexus IS F is a fun car, isn't it? 👍😊

That's pretty darn expensive for a 10 hp gain. Better to put those $$ towards the next toy.

Not to shabby, how many miles are on the car?

Im seeing so many people questioning the +9 or 10+ HP he gained... Basically that ecu from RR racing is suppose to give you a bunch of power but there are things that you need to have on point like, PPE headers, rr intake, invidia exhaust or custom exhaust. If you have this beginners MODs on this car he could gain like +50 to +80 or even more, but since he has his car stock so that’s the result.. This kind of ECU you need to run 50 to 100 miles that’s like the way the car with this new ECU will be learning and gaining more HP. All this mods, methanol, nitro and a turbo supercharger kit you could make +600hp easy to this beautiful V8

Considering what a brake job costs for these cars, I don't think the $700 is out of line to push you past the ISF next to you.

If you sold 4 cars are you into something bigger ?

Thanks for doing this test. I think it's way too costly for an 8 hp gain.

In the rally world guys spend thousands to gain a second no big deal spending to get what you want ..

At 1'32": For NA cars it is MUCH harder!

$700 for 10 hp? how can you be happy with it?

For what RRACING charges for the tune it's not impressive on a NA engine..

Get an updated front and rear bumper then more exhaust and engine mods

Which part of Ohio are you in?

Nice!

I’ll rather get the burble tune from M Tune for all that
