    I need some opinions on a plug reading. I just pulled out autolite 45s and installed AR33s (Two ranges colder). The picture below is with 11 psi with 18 degrees of timing. I also added a snapshot of my spark table if i can get some inputs that would be much appreciated.

    Specs: 390 8.5 comp, T76, intercooler, AFR under boost is in the 10.8 range, IAT roughly 130 degrees F.

    Looks good to me, given they only have one pass on them.
