Only 1 & 3 cylinder "forward" spark plug are fouling. ALL of the rest of the spark plugs look perfect. If it was the tune, all of them would be fouling out as well. I could just change those two spark plugs before getting the tune adjusted. Have to admit, this thing rips now even with just 6psi boost. Finally got the right combination of cam and turbo. Just need to get the tc tightened up a little.
