So my check engine light keeps going on and off since i got my borla S.. its annoying and when its on everything is all screwed up .. remote start works and turns off 5 seconds later, sunroof and windows sometimes are auto.. just a pain in and around the anus..

back when i had a 04 sti, i had a access port tune and i was able to check the code for the check engine and reset the engine light and turn it off..

Is their and access port tune or anything like that for the GCSRT ?

check out the diablosport predator and the trinity they will both do what you want them to

ok ill look around, thanks for response

what the average HP and Tq gain from the diablo ?

I wouldn't think too much man.. I mean you will notice a little difference when you add the 91 or 93 tune... but when you add Johan's tune that my friend is when you will notice:eek: you won't even think its the same ride :lol:

I wouldn't think the exhaust would cause a code. If you don't want to take it to the dealership, usually the local autoparts store will read your codes for free.
