re-gapped all plugs to .025 . checked fuel pressure at idle(~35psi) and at full boost (~65psi). rechecked timing and put at 15btdc. made tps voltage .43V . the only thing i really found was a loose O2 sensor maybe causing an exhaust leak.

anyway the car still breaks up under full power at 4krpms .

do i have a bad CAS or PTU? the car runs flawless except this high rpm hesitation.
My eyes are bleeding from reading high rpm hesitation posts... and i am STUMPED. whats bad is the car was a complete rocket when she got put back together and now since its time to dyno she wont cooperate.
