I'll try to get some stuff posted as soon as I can. That's cool, I won't worry about the computer - had to ask though. Man, i'm sure it's just mental (as just doing the muffs is basically a "sound" mod) but it just seems to want to pull a tad more. If anything it doesn't seem as labored up in the higher revs. 1-2 HP maybe? Hey, I need all I can get on the first gen. 4.6
