How much Boost should I run? (boostcreep)

3" exhaust from the 2g o2 housing all the way back, also no cat

I’m going to pull the turbine side of the turbo and try to port that out some more, to better match the porting on the o2 housing. according to this tech artice and I’ I’ll let yinz know if it fixes the problem.

Its a creep,
my car is boosting to 11lbs (actuator set) and as I get to 4k+ the boost just keeps rising, and rising.
