Asa, the guy I talked to with a v8 throttle bodies v6 saw mpg improvement. Don't ask me how cause I've never done it lol

With a ported head, ported throttle body, and ported exh manifold my Neon got an extra 4mpg and a very feelable power boost. I've been driving it that way for 200K miles now - so that work paid off...lol
