Ok, I'm chilled. I have a feeling one or more of the plates have turned / bent and are covering up/ restricting intake flow. While tuning on Thurs eve, the engine had a few hiccups ( backfires) at part throttle and those in the past have caused blown intake gaskets. Imagine the pressure in the intake.

I drove it yest afternoon to pick up the daughter from work and at low throttles it runs good, it like a cork has been thrown in it for boost. Tom
