I run with a MP PCM, Champion Truck plugs and 180 tstat during the racing
season. I'll be putting back the stock tstat (colder weather in my area)
and stock PCM (less power for slick wet/snowy streets) once the track closes.

I have read conflicting articles about plug ranges ... one advocates the
traditional colder plugs for track use or detonation problems ... the other
says to go to hotter plugs because of the 'new' technology of EFI, today's
lower gas mixture and emission setups. Naturally, all depend on whether
plugs foul up, etc. Who knows what to believe?
