more horsepower = more frequent hell rides and runs up to 7000 rpms = more gas consumed

i dont know, ive heard people claim more mileage from intake and some ads claim hp + mpg improvements but i tend to agree more with will, its a simple formula air+fuel=power, more air = more fuel.... you probably wont find a way to make substantial power without sacrificing gas mileage BUT simple stuff like exhaust/header/intake wont make that much of a difference... you probably wont even notice
