LB7: Lb7 turbo question

[dcpjfs432]

Okay so I have a 04 lb7 as far as I know it is stock other than a k&n cold air intake. But it is pushing 37psi of boost which I thought was high for stock so my question is what should it be and how do I go about diagnosing this issue? Thanks in advance

How do you know it’s 37psi?

2x ^^

How did you read the boost

37psi - 14.7psi = 22.3 if read from boost sensor. Not high

If you want to see exactly what the turbo is putting out, put in a mechanical gage.
