Message I finally got the Z out, runs great idles perfect, no codes, but one problem. I cannot boost over 7-9 psi, with the boost controller on LO, HI and off. I don't have the factory boost solenoids in the car. when I step on the gas and as soon as it hits 9psi the car feels like it's bouncing off the rev limiter (only way I could describe it). I cleaned the solenoid for the EBC.

It was running perfect last year before I put it away. The only things I have done to it over the winter was sold the doolz intake I had, added a 2nd MAF, and the Selin kit and the settings are correct on that. Could it be a bad MAF, but wouldn't it run rough all the time?

Thank you
