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?
 
actual tune made 235 whp weather corrected 250 wtq (weather corrected) had him come with me i boosted, and the scanner said no knock, but was showing misfires, anyway from 6 to 60 at some times. and it was weird because at some points it hit 13 lbs of boost, which is 3 lbs over what the tune said it made.... and yeah im running 180 t stat and tr6s
 
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
 


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.
