Message	The motor would start fine, idle fine, run fine, pull fine...until I hit 18+ psi. It felt like I was hitting the rev limiter. It would be worse at higher psi. The motor would pull fine if I rolled into the throttle. WOT and 18+ psi it was horrible. I changed plugs, checked for boost leaks, checked throttle, cleaned MAS, then changed MAS, changed CAS, fuel pressure is good, AFR good. Changed coil packs and bingo. #6 is on it's way out. notice the "blow out" area between the screw heads on the right coilpack compared with good coilpack on the left. Hope this helps someone in the future chasing a similiar problem.
