Time for new plugs and wires...also check for boost leaks.

ive got a very simular problem. after like 3000 rpm everything is perfectly fine..


since ive replace

coils
plugs
wires
ecu

the only think i havnt tried is the cas.. this is righ after engine swap mind you.. mabey would a loose ground cause this? i know everything is hooked up correctly, except the ac (removed lines and all) and i also have the egr blocked off and silinoids removed.. hmm any ideas?
