I have a 1994 extended cab Chevy K2500 with 123k miles 3.73 gearing and its still stock and its last tune up was at 110k miles.

I'm looking for a little bit more acceleration and low end nothing major or over say, 500 bucks since I'm on a low budget right now as I am in high school. I will be adding just a Flowmaster 40 muffler soon and I did upgrade the air intake tube to one of those long tubes without the silencer box. Is it possible to get a mild cam that WON'T include any other modifying and that will improve exactly what I'm looking for without killing the fuel economy too much?

Also do you think another tune up would help any before doing anything else?
thanks.
