I am having a problem with my boost not hitting the set target of 18-19 psi peak. SS has my car setup with a prodrive boost curve that hits 19 peak and then tapers to 14.5 at redline. The problem is that lately I have noticed that my boost will only peak to about 16.5. I have tried both maps I have and still have this problem. This is also the second time I have had this happen since my original tune. I was wondering if anyone else has had the problem or knows where it could be leaking from. I'll be calling ss on this, but just wanted to see if anyone had any other ideas. My setup is tbe, up, and ecutek. Thanks.
