Mine is just EGR delete, gutted the smog pump but still there as a pulley and for looks. most emission lines and solenoids are unhooked. Had the heads rebuilt with a good 3 angle valve job milled just for clean up, still has stock turbo set at 10-10.5psi, also stock down pipe but had no other exhaust for some test & tune runs, has mufflers now.

Do you hear any detonation with 10psi?

I'm at 7-8 after bending my wastegate bracket(TTA advice). Now it runs so good with the carb rebuilt I'm going to bend it back and try 9-10.

I do get a slight pinging at WOT under full boost but none or not audible at 3/4-7/8 throttle or when the boost is under 8-9psi.

This is with normal 91 octane gas, havent tried 93 with 10% ethanol yet, but now that the car is full exhaust I dont usually do any WOT or high RPM runs on the street, its too nice of a low mile pace car to mess with racing or max boost, the test & tunes were just for fun to see what it would do, very happy with times that are almost 2 full seconds faster than recorded stock times with a professional driver... & mine is 99% stock still.
