Some advice about my WRX
I got my 07 WRX 3 months ago, and ive done some modifications on it:
1st i remaped my ecu by ECUTEK
2nd i installed supersprint exhaust down-pipe centerpipe and the rear part silencer;
and ive upgraded my brakes to brembo, and i bought a short shifter, and lower springs.
My technician says i have around 270bhp, i had 1.29bar before i installed my forge BOV, now it droped to 1.15, does anyone know why?? and what i dislike after all ive done is that i have a lot of under-stearing. Does anyone know what i can do to solve this issue of handeling?? thanks..
