A .045 is an extremely huge gap to run on an FI'd motor. I experienced blown-out spark at .040. I don't have alot done outside of the S/C, currently. I am not using a larger MAF or Mustang TB. I have an optimized TB and stock manifolds (Yes, I even have the Cats) on a fair sized (Bassani) exhaust with a custom y-pipe. We have tractor gas here in AZ, but I mix with racing gas to equal 94 or so.
BTW- Fst4Dr- How fast is too fast when you speak of plugs wearing out? They change in a snap and they are cheap as hell, relatively speaking.
