15 STi CWP | 02 STi Wagon

Default 2015 WRX | Stock | Cobb Stage 1 | Stage 1 PROtune | BrenTuning

Car: 2015 WRX 6MT
Tuner: BrenTuning
Dyno Info: Mustang MD150
Transmission: 6-Speed
Gear: 3rd
Peak HP at RPM: 270WHP @ 5550RPM
Peak Torque at RPM: 288WTQ @ ~4050RPM
Baseline HP/TQ for stock on same dyno: 217WHP/228WTQ
Target Boost: ~21
Target AFR: ~11.0
Fuel: 93 Octane


At WBM 2014, I entered the raffle for a Cobb Accessport, it was for a car that at the time, I didn't even own, but I knew it would be coming in and I knew that I can't keep anything stock. I ended up winning the raffle and the AP sat on my desk for a month. Once I received the car I enjoyed it stock for a little while until the maps were released. Once released I immediately downloaded them and flashed to my car. I could notice a difference in power immediately, although not as much as in the EJ, I knew it would get better with a protune -- and that it did.

Bren and I had been talking for a while and I had been pestering him on what seemed like a daily basis on the release of ATP. The day that it was released I sent him some logs, he did some wizardry and a couple hours later I had an updated map to flash to my car. The difference between his map and the OTS map was immediately noticeable -- more noticeable than flashing from OEM to OTS stage 1. The car pulled much harder up top and came on much quicker. We tossed a couple logs and revisions back and forth before finally finding some time to get the car on the dyno and tweak it that much more. The results speak for themselves.

Impressions:

The car pulls great through all the gears and is a HUGE improvement over the OTS maps. Where OTS would lug in 6th on the highway, this map is smooth and I never feel the need to downshift. Power is linear and torque comes on quickly. Many people complained about the OTS throttle mapping, something which took time for me to adjust to as well. With this map the throttle input is the same as OTS, but it isn't an issue, it feels OEM in sensitivity while still having full control of throttle input. I took a 150 mile trip the day after getting her off the dyno and averaged 37MPG on the readout! This was over hilly terrain ranging from 50-70MPH, I couldn't believe it, I never saw close to that stock or OTS.

This car made:

Stock: 217WHP/228WTQ
Cobb: 236WHP/239WTQ
PROtune: 270WHP/288WTQ

It made 53WHP/60WTQ (peak) over stock with gains in the midrange as high as 70WTQ! Enough typing, I'll get on with the pictures!

Bren will dyno or e-tune the car, obviously best gains with a dyno tune.

That must be a very aggressive custom tune. I haven't seen any 2015's with that large of gains from a custom tune yet.

Irregardless of your tune, I would think doing pulls in 6th at highway speed is still bad news for your engine.

That's some good power coming out of the new engine....My 2013 wrx had similar numbers with a Stage 1 Protune from EFI LOGICS....270whp/296wtq...

Cant wait to see what they put down with a full turboback exhaust....

Fantastic!

Bren does great work, safe tunes. He's quite excellent optimizing dual AVCS. I'm not surprised on the gains given the turbo location, EL headers, and cams.

Nice gains OP . The only thing that kept me from buying the WRX over the STI was availability.

Ok douche tards. You both are right..
http://www.merriam-webster.com/dictionary/irregardless: Irregardless originated in dialectal American speech in the early 20th century. Its fairly widespread use in speech called it to the attention of usage commentators as early as 1927. The most frequently repeated remark about it is that “there is no such word.” There is such a word, however. It is still used primarily in speech, although it can be found from time to time in edited prose. Its reputation has not risen over the years, and it is still a long way from general acceptance. Use regardless instead.
Now, back to the subject...
Are these gains possible with a Cobb Tuner using an updated map?

Toph, great post and GREAT GAINS! My LORD....this is JUST a tune? 53WHP with a tune? WOW, add in a intake, exhuast, and downpipe and the WRX looks like it could become a monster.

On another note...MY LORD Subaru...why do you hate us so much? Lol
