Anyone had this problem?

[95GreenGST]

Why everytime boost wants to kick in on my B16g, it feels like my ECU fights it? Sometimes it will boost good. But 95% of the time it will start building boost to 10 and jump to 12 then to 10 then spikes from 4500+ RPM to 14-15psi? If the boost stays under 10 then it feels strong but when it goes over 10 it feels slower.... Damn it! Someone help me please! I have no boost controller but I just installed the 14 psi wastegate actuator to controller it to 14.

Ow yeah when it does do the slow thing the exhuast gets loud and the car goes no where. You can here like a faint UDDDDDDDDDDD sound or something like that till I shift then it comes on strong after the shift.... then 10+ psi or 4500+ RPM same slow thing..... Does it more in the day, and not all the time. PLEASE HELP!!!!!!!!!!

sounds like your car is retarding the timing when you reach 10psi. have your base timing adjusted and see if the problem goes away
