Hey VW community! It is my first time doing a thread and let me explain.
I have a 08 GTI stage 3+ APR fully built with aux lpfp and upgraded hpfp. Ive been having the Low fuel rail pressure for a while. Now, i found my boost leaks and today i believe i got em all. Once i fixed my big leaks,all of the sudden, the car starts doing a really loud bang and hard jerk movement when i wanna boost fast past 13 psi. It also showed more codes. I thought the leaks were going to solve the code for low pressure but now there is so much pressure it is making that loud bang. Cam follower is good, changed a couple of sensors, tested the in-tank pump and it is working. I can drive it without accelerating hard and if i try to go past the loud bang it just does not hold pressure and fluctuates all crazy. Im trying to include all i can for you all to help me brainstorm because it has been a while since ive had fun in my baby. Need some help. Thank you.
ps i took a video of rail pressure, injection timing, boost pressure and others while idling and pressing on gas but it does not let me attach a video.
