Mine are gapped at .032 and no issues so far...I would gap closer at .028 - .030 if running more than 12lbs

I'd recommend .028'ish. That's what we run with our turbo Jeeps and haven't had any issues so far. If you're running 1-10psi, go 1 step colder on the plugs, 11-20psi go 2 steps colder on the plugs. That's what we were told by NGK.
