after dropping to a 3.5 pulley with a tune i have been having the same issue with my car, it hesitates and misfires under boost, it happens just on cyl 6 so i thought it was the EGR so i did the EGR blockoff since it dumped into cyl 6. but its still happening, what should i check next. i have also checked the coil packs, plugs and wires.

KR and timing.
Did you get an actual tune or a pcm from somewhere?
You running a 180* tstat and colder plugs?

Im gettin almost the same thing...Cylinder 5 and 6 misfires at idle only though. The 6 is at about 40 at idle and slight throttle. But moderate throttle and above I have 0 misfires

that could be injectors maybe.

about 40 at idle and slight throttlewhat are the numbers you're talking about, number of missfires? how would you check that, with a scanner?anyway from 6 to 60 at some times

They are the number of misfires in a cylinder per minute. I have an aeroforce scan gauge so I can keep an eye on each cylinder. My cylinder 6 misfire is gone after replacing the blown out plug.
