ok guys.. finally got MSD. did a search... nothing. i remember people sayin that once u upgrade to a MSD amp... you change your spark plug gap back to stock. is this correct? i just want to make sure before i start screwing around with my new plugs.

im currently running a DRAG3 kit (LS). im usin NGK BCPR7ES11 plugs gapped at .34-.35

also, out of curiosity... would running a larger gap on these plugs and the combination of the MSD/external coil increase engine temperatures (hotter)?

I am sure I posted MSD gaps before.

MSD + NA = 0.50 gap
MSD + boost under 8 psi = stock gap
MSD + boost over 8 psi = 0.34 max

Best bet is to keep increasing the gap slightly until you start to get high boost misses, then back it down a hair. The MSD will not effect engine temperature.

Good job on the plugs, keep the 7 series unless you are running no intercooler, then think about 8 series.

thanks!
