Anyone know what standard boost is on a V4 Sti?? Not sure if mine is high or not but its never had any issues. My car is standard but i keep getting told its to quick to be stanard by people near me (because they couldn't catch me).
Thanks

 

Hi mate, my V4 STi peaks at 1.5bar then settles down to 1.3bar. Not sure if mines tweaked or not ie: no signs of the boost solenoid being altered, havent looked at the ecu yet to see if thats been modified or not. All im running is custom 3" exhaust with milltek de-cat and apexi panel filter.

Its been running like that since i bought nearly i year ago and its been spot on, also im using an knock-link and only ever had 1 orange light on!!!

Regards
Paul

 

should be 15psi standard

 

In standard set up it should hold 1.1bar (approx 15psi)

 

nice one guys. mine peaks at 1.27 then backs down about 1
