this is funy couse i had my car mapped last week and i said to the guy how was mapping my car why isnt my car boost creeping when every other starlet out there is.Im boosting at just under 15psi and it holds at just under 15psi all the why to the red line it made 196.4bhp on stock ct9 without porting the wastgate i just couldnt understand why the boost holds so well?.So i had a good look around and found that my hks actuator arm was bending as the wastgate opened i gess as the wastgate is opening and bending the arm on the actuator it is keeping the dieafram at a sertion level so it just wont creep lol that was hard to spit out lmao
