What should I tune first on 04 Mazda 3 2.0L


is the word, beotch
Ground the throttle body, add a CAI or SRI and a K&N air filter. If you have the cash for a free flowing exhaust, that might help a little too, but you aren't going to get a whole lot of power out of it without adding a turbo etc, which is a lot more money. Buy an MS3 if you want fast.

You could look at doing a Standback for the MZ3. Tuning might get you some HP, but you need to know what you are doing :) I personally have a CPE Standback that I love for my MS3, but that is no longer made.
