Turbo Peak PSI?

What is the turbo supposed to spool to? Mine never seems to get past 30k. I swore when I test drove one of them, it hit 40k. Did I just see something wrong? Or is mine not spooling up as high as it should?

When mine was stock, I would see about 37 psi max. Now I see about 45psi.

Based on you saying it got 37, i called the dealer and said I was concerned I was only hitting what appears to be 29. Never crosses 30 for sure. The service guy said 32 psi was stock max. Can anyone else confirm or deny?

My truck is a manual so I don't know if that makes any difference or not.

no joke! at midnight the other night, it was 90 degrees and 95% humidity. and then the following four weeks were all over 103.

and stock, my truck would hit around 34-37psi. now i see somewhere around 50.
