Currently just bought a 04 srt4. Had an agp wastegate and a boost controller next to each other. Took it to Howard's House to check it out. (they removed the boost controller) Because I was boosting well over 22+psi on stock turbo and was surging.
Loosened the adjuster nut and it was back to stock psi and everything was fine.
Fast forward two days later and its making the surging sound/movement (while on boost 22psi+) on my way to work.
My questions is there a way to make it stay at stock psi without having to adjust it again if its the same issue?
Its either that nut tightens itself which realistically doesn't make sense or I have a boost leak? How do I check for that?
