hello to all sifu,
before this my car is running 0.8 bar boost, and in gear 3, at 4000 rpm, the car will jerk for about 3-5 second before continue to blast. Then I switch back to stock boost controller, running stock boost, the problem still there. It will jerk at 5000 rpm, jerking for about 1 second, then continue to blast.
It that the sign of dying fuel pump? or faulty MAF sensor? how should i start to troubleshoot?
