its prob a mix of the tune and a boost leak. Boost leaks cause premature boost cut. running only 10pSI shouldnt do it. BTW unless you have a wideband o2 and gauge you cant tune the car yourself.

Go to www.vfaq.com and look under the intake section and there is a write up on how to make a boost leak tester and how to use it.

yeah sounds like a boost leak. You wont hit fuel cut unless your under load. So if you stay off the turbo youll be fine. Do a boost leak test and be done with it lol
