Hello,

I am new here, as well as a new WRX owner. The car is incredible, but I see so much potential for power with little cost. My question is for all of you stage 1 or 2 WRX owners, how does the car handle the additional power? Granted you do not beat the living crap out of it, can the clutch handle the torque without slipping? What about the differentials etc? I had a GTI which I tuned, 3 months later the clutch was slipping. The WRX feels infinitely more solid, but you never know!

My older one has had a tune and a dp for a good long while and the clutch doesnt slip. Although I bought mine as a basket case, it runs well.

My local pro tuner said the connecting rods on the FA20DIT are weak so he will not tune vehicles with that engine.

Tuner up here in mn says the same thing. [email protected] will tune though, as long as the waiver is signed. Lol

I've had my 16' stage ~1.5 ( just a j-pipe) for over a year now. Makes 260whp/290wtq with no problems. Make sure you get it tuned correctly, I'm not a fan of the OTS tunes.

Strange to hear this...From all the reading Ive done on here it sounds like these cars are meant to be tuned and its relatively safe and reliable.

I had mine tuned stage 1 with no problems other than the tune itself which is being fixed because of fine knock readings. I switched to the Cobb Stage 1 V301 HWG 93 Octane and it runs very well. No knock, pulls hard through the revs/gears, no lag. No rev hang and the turbo is linear with the throttle.
I got 252 AWHP and 281 TQ

I would recommend the OTS Stage 1 map from Cobb APv3 all day long over the stock tune. Very impressive IMO with a completely stock car.

I have a tuner coming end of September but not sure what I can get done by then,still waiting on 2017 AP firmware patch,not sure whether to tune stock or try and get exhaust,deletes,ebcs and aos in before tune.

I'm sitting at 297whp/321tq no problems on my 2015. From what I've been told by several tuners, connecting rods are definitely the weak link and seem to fail after 400whp. The rods for a typical stage 2 build are sufficient.

What supporting mods ?never mind I followed your link

Stick to a ProTune for longevity. You may request a more conservative/safe tune from your tuner as well. Stay away from OTS tunes if you want the safest route.

I went with a pro tune myself and the car runs great. I did find out that the tuner actually started with the Cobb OTS map as a baseline then tuned from there. I ran the stock Cobb93 v301 HWG tune and experienced no knock and DAM stayed at 1. No issues whatsoever, and was WAY better than the stock tune, but not as much snot as the pro tune. With the Cobb OTS map you really have to mash the pedal to get all the boost. If they could front load that boost a bit it would be a better OTS tune IMO.

Just play it safe until you're ready to pay big. The 300whp mark seems to be pretty safe. Most of the blown engines reported on here were tuned above 350whp and running E85. It all really boils down to how much money you have to blow.

These cars aren't meant to be tuned. No car is meant to be tuned. They are built to handle the stock power for an extended period of time. Anything over that and you lessen the life of the motor. The phrase "you have to pay to play" always sticks.


Now, as others have said, some have found that the rods cant handle much power over 350-400 torque. However, from what I've seen this new motor handles your simple power bolt ons like J-pipe and intake fairly well. Keep in mind, we are still in the beginning of the life of these new motors. This means that not much is known yet about their true longevity and more importantly how long they hold up with more power.

just learning this COBB V3 stuff, pardon my ignorance. Do you need a tune with just the access port V3?
