15 psi is around 1 bar isn't it.
A few months ago i had a problem installing the bleedvalve, they gave my wrong instructions. After i installed the bleedvalve the car was running at 1.5 bar boost was real fun till my pistons were not round anymore The car didn't get enough feul. So i went to a tuner in holland and he said it was impossible to run so much boost without a other ECU but as far a i know mine is orginal....
So i am thinking to get a fifth injector as well and a oilbreather and swirlpot.
but i think it is going to cost losts of $$
can anybody give my a price???
