Just picked up a 13 gsr 6 weeks ago and I'm ready to start pulling in power. I'm looking to get 340whp as a start and keep doing my research to decider on what to do after that. I'm looking to install ams catback single exit, ets test pipe, ets open dump dp, 3 port boost solenoid and of course pro tuned by efi logics in Connecticut. What would I be looking at power wise after this tune?

A few months later I will be installing 4" ams Fmic, uicp, licp, and also a AMS intake be retuned at efi. Also how much more power out of this.

After this will be a fork in the road for me, but I assume this would be enough power to hold me off for a while and start working on aesthetics. Thanks guys

 

What kind of fuel? 91, 93, E85?

 

with the 3 inch full exhaust from the dp, you might get around 320 but i do not think you will hit 340..i have full intercooler piping, 3 inch from dp, intake and ebcs on a 91 tune i hit like 355 whp.

 

What kind of fuel?

 

I had 340 on my 2013 with just a 3 port and a tune from English Racing. My guess is that with a test pipe, 3 port, and tune you can get to 340. Mine was sort of a factory freak, but a 3 port and TP are the first two mods in my opinion. Intakes and the intercooler piping do little to nothing to add HP on a stock turbo from everything I have seen.

 

Could be close... each car, tuner, dyno is different. I have similar mods and just dyno'd at 320/330 on 92 octane at 26psi.
