Do you have any questions? Let us know and we'll get them answered by COBB

I so glad I found this channel. I am running the MaPerformance tune, but I still love the cobb stuff and these vids and info I'm getting from these. damn good vids

The way this channel is managed is 10/10, I'm not the type to ever comment on videos but I have to give props, definitely subscribed. You've helped me a lot in the process of my build. Thanks!

From what I understand, all of the peak hp and torque numbers drop in high rpm because the air going into the engine gets too hot as you pull through a gear. When this happens, the ECU will start pulling timing and boost to save the engine from damage. Heat=bad. The main fix for this is a larger intercooler to keep the air temp down while pulling through the gears, then your ECU will like what it sees and give you the numbers you are looking for, assuming you are tuned for it. You can only tune so much before having to do this upgrade.

Thank you so much for this video! It answered so many of my questions and clarified many things for me! I currently own a 2021 WRX Limited and get so frustrated with its power output from being somewhat aggressive to just plain dull at times. I now run 91-93 octane in it and it seems to be more consistent in its performance. I’ll for sure be upgrading to a access port 91 tune then later a stage 2 in the near future. I want to motor to stay safe and reliable. I’m confident now after learning more that I’ll see nice gains and a more consistent power output when I tune the car. Thanks guys !

this is great .Getting the cobb engineers in the house too .I really needed a channel like this .Im stock atm just catback exh and on panel filter .I wish we could put a cai kit without having to tune it though but il hoard parts then get the cobb ap and custom tune done all at once

Going with a stage 1 etune from a local tuner, should be the best tune I can get without a dyno!

What’s happening with this FA WRX guys? Was looking forward to seeing it’s progress and updates?

I wish you would do a video on negative ignition correction explaining it and showing when you need to be concerned and when negative ignition correction is ok and not a concern. Too many people in the Ford Mustang forum tell everyone that any negative ignition correction is bad and you will blow up your engine. My understanding of negative ignition correction is it is the ECU monitoring for engine knock/pre ignition and it pulls timing and that is where your negative ignition correction comes from. Again from my understanding a problem would be when the gauge shows constant negative ignition correction i.e. the gauge reads negative ignition correction for long periods of time and or has a large amount (number) for negative ignition correction. Some of the Ford owners brag that they never see negative ignition correction, I would think the reason they never see negative ignition correction is because their tuner has went the safe route and back off the tune thereby leaving some power on the table. I have a 2021 Ford Mustang 2.3L High Performance Package so it has the upgraded parts from the discontinued Ford Focus RS so it is a little more robust package than the standard 2.3 liter Mustang engine. On my Mustang 2.3L HPP I can see small amounts of negative ignition correction for individual cylinders but when I monitor overall ignition timing I never see negative ignition correction on the gauge. What negative ignition correction I see on individual cylinders is minor and will only show up for a split second either when accelerating from a stop or on deceleration it will again for a split second show negative ignition correction. Also I see that COBB seems to use cylinder number 1 on the 2.3L Mustang on their tunes, so wouldn't that be the best cylinder to monitor by the customer as well? Some say monitor cylinder 3, others say cylinders 2 and 3 and still others say 1 and 4 and finally you have those who say monitor all four cylinders. They are just all over the place so what you read on the forums becomes less than helpful.

Great videos... good information on stock wrx. I have the 2018 premium with sti sports package 6spd. Shrtthrw... still stock for now besides exterior.. going to get Cobb stage1 package soon. Thanks for your comments.. good stuff.

Great video! Just went stage 1+ cobb

It seems like with the COBB OTS stage 1 tune, boost is delivered more effectively, every time. I can almost always hit peak of 19psi with a tune but with the stock tune sometimes my car would struggle to get 14-15lbs of boost. Also, my Focus ST had a stock FMIC and it suffered from heat soak, bad. Worse than my TMIC wrx. I think maybe the size of the IC and the piping has something to do with it too.

I see a lot of people saying the basic tunes that come on the Cobb access port sucks. Is that true.

Great info thanks gentlemen 🤘🏾🤘🏾

Love the idea of an extra 100 hp just from flex fuel. I assume this works on older WRXs too? I have an 09 with tons of recent maintenance done, new Accessport, and itching for a tune! :D

Got a pro tune right when I got my 14 Wrx. Drives 100000x better.

Wow Mike from innovative buffalo NY. Hi

I have a question the COBB stage 1 91 octane tune, Is this tune designed to work with the stock airbox and exhaust and just fine tunes the ECU with stock parts? Its my understanding the stage 1+ tune is designed for an intake, What exactly is the difference between Stage 1 and Stage 1+ with the 91 octane tune?

Does E-85 deteriorate the stock fuel lines/fuel system on 2018+ WRXs?

What causes these Wrx’s to have issues with a/f mixtures. Seems to be a common issue shortly after tuning. Within 15,000 miles

-20 I give my sti like 10 seconds to warm up but I drive slow for at least 15 minutes. 150k on stock engine and stock turbo baby

My Gd Sti made that kind of power stock. Thats an impressive number. Do you use different dccd settings for different dynos? Linked and unlinked rollers for example.

Was this tuned on a dyno jet? I got tuned on a mustang so my WHP was 234 and WTQ 268. What would that read on a dyno jet? 15%-20% more than a mustang? My tuner says 20% but when I look online it’s 10%-12% more?

I just got a stock 2018 WRX 6spd manual a month ago with 66k miles and looking to just getting a ots 91 octane stage 1, so my question is what hp and tq gains will I see? Thanks

Seriously with e85 and a tune I could put down roughly 100 more horsepower overstock? Do you recommend an intake and exhaust as well? I have a 2018 and I'm using a cobb 93 stage 1+ tune w/ intake and an axel back exhaust. Been on it for a year and loving it; Hung with an STI on the highway. Love this car.

What map should I use with just an k&n drop air filter? Everything else is stock.

Sorry for the noob question but would the Cobb stage 1 or 1+ work with a grimspeed drop in filter?

Is there a OTS Cobb map for Cobb intake, Perrin fmic, Cobb bpv and stock exhaust?

I have a 2021 STI, with a cobb intake and stage one ots tune how many ponies will it add on 93 octane over stock??

Getting my 2020 WRX Premium soon. If I use 93 octane all the time, even being stock, will I have more consistent WHP and TQ? Ill be getting the Cobb Accessport shortly after i get my new WRX. Thank for the informative video.

Intake - tune - exhaust - e85 - clutch

Great info!

Does the car limit boost in below zero weather? To 16.5

Will cob tunning my sti with basic Bolton’s void warranty ?

Will a Cobb tune affect MPG?

How much horse can a stock clutch hold?

Ahhh the damn knock my krypotonite. 😡

Hey guys, I have a WRX it has 140,000 miles on it. Would it be smart to run a stage one tune

Your guys got some dope parts and accessories , but you Maps for the wrx are trash sorry guys IJS ..

mhm *sniff... mhm *sniff

Run 93oct here in OH. I take it the Cobb AP (stage 0) would help my car act/perform more consistently? Merging on to the hwy (near full throttle), I can feel the car pull back (stutter); is that the factory ecu being safe, protecting the engine? How do the tunes work at 0*F (or colder)?
