I'm looking for the people with tons of mods to chime in, after the basic bolt-ons (MPIII/MPX,TB's FMIC's, Exhaust,OD on the blower ect ect) Where do you look next? Heads? I was looking at the Coy Miller heads and they are not cheap. I know that the IM can be ported at the plenum and at each runner. so people that have done the big mods please chime in and help me weed out what works and what doesnt work.
