Hi! I have audi 100 c3 2.3e with injvent jetronic ran fine. But now swaped 2.2turbo mc1 engine, changed MAP sensor to 400kba sensor, car run fine till 4000rpm after that starts to pop and bang like launch control . If i put really weak spring in wastegate 0.3 bar car will go over 4000rpm but with really low power. Are bosch 502 injectors too small for turbo engine or am i missing something ?
