i installed a mopar stage 3 turbo manifold and turbo. after i got the installation complete. i took it for a test run, i gave it about half throttle and the car fell on its face.My car could drive, but I cant accelerate at all. i have no power, I was a turtle. When I put my car in neutral/push in the clutch, I can rev like crazy. But if I'm in gear and I try to go, my RPMs go up so slow and I accelerate like a handicap cart in Walmart. since this, i have 0 yes 0 boost. i have looked at every connection multiple times for boost leaks checked the turbo( no shaft play), checked the timing, changed the 02 sensors, coil pack and wires, is there anything im missng here. my car has been down for like 3 weeks and im about to lose the loaner i got.

thanks
