Problem with missing/bogging above 6 psi I'm having a problem with my motor missing or bogging when I get above about 6 or 7 psi on the turbo. I can run 6-7 psi WOT and it's fine, but part throttle has a few issues, and WOT above about 6 psi has issues. Scanner is not showing any KR, and I'm only running 11* of timing right now, so it should be fine. AFR is right about 11.5, I'm using TR6 plugs gapped to .035, and stock plug wires. I have no idea what's going on......anyone have any ideas? It accelerates well until I hit a certain boost level then feels like it starts to stutter or something. SCR is about 9.5:1 and DCR is about 7.0:1 and I'm running 91 octane, no meth right now. Wastegate is plumbed into the intake manifold behind the throttle body.

Have you read the plugs after a hit? What is your fuel pressure? You running the maf or are you in SD? Have any logs? Sorry for all the questions. Trying to help you out.

I do have some logs, I'll see if I can post them when I get home later. I haven't pulled the plugs yet after a hit. Fuel pressure is good, about 65 psi. I am running 2bar OLSD.
