Tuned PCM which spark plug?
What plug should I put in with a tuned PCM, CAI, resonator delete and aftermarket cat? I think I had NGK's in it before the tuned PCM and it was running great but one of them fouled out and I'm replacing them now and I need wires. Should I stick with the NGK's and what should the gap be?

Stock plugs, stock gap IMO. That's not really enough mods to change the heat range of plug needed.

Unless the PCM was tuned for different plugs/gaps, then go for stock.
AC Delco or NGK is your best bet.
