Ok, laugh it up now if i made a big mistake for buying one, but i figured i would give one a try, its made by Procomp i'm sure, its for a SB, they have 2 styles, i went with the large cap unit with everything in one for 72.00 bucks, it takes all GM parts, so if something goes bad, i can replace it with GM stuff, it comes with an adj. canister, my question is, is anyone useing one of these, any feedback, i'm hopeing it clears the firewall in the Dart.
