    Could my cat be plugged enough to keep it from being spooled up? Like it's being choked out

    From what you're describing, I'd guess it is a wastegate problem

    I think my wastegate is getting weak, it held 28psi all summer. Depending on how my dot goes next weekend I might be getting a pdi turbo and tune. This truck reminds me of my roehl company truck. Slow as hell and couldn't pull a hill in 10th.

    Mine has been having a major surging issue for the last couple months. I have my wastegate line disconnected and that made a big difference in pressure. Went from 24 to 30 right away. My turbo keeps coming loose...jyst about to replace the 2nd gasket in 4 months...

    Mine is very consistent, no surging, but I used to be able to peg the boost at 28 psi on my 2KS, now I'm lucky if I can crack 24 on a cool, dry night. I tried kinking the wastegate tube and it made no difference. Been on a Cat ET ride, cutout test looks great, CAC and boots replaced, turbo inspected by Cat. Do turbos get lazy at end of life? Is that a thing?
