In turn caused by the fuel pressure set wrong or somthing else.

One of the oxy sensors doesn't look too good either.

Stock sparkplugs on mine too.

I was wondering about that trim reading as well. I will just swap out these iridiums for some good ol' copper plugs as soon as I get the chance to do so and re log it to see if anything changes.

New plugs and voila, no more problem. Swapped the plugs out to some coppers @ .039 and they work great, thanks again Eric. Next is to up the boost some more and see if I get blowout passed 12 psi. :) Woop!
