I just recently got an 07 ms3 and was wondering what i could do to get atleast another 20hp. The guy that had it before already did a cold air intake so thats outta the picture. I am open to any suggestions and i also am kinda on a tight budget. thanks

 

i've found a hypertech power programmer on corksport's website for the 06-09 mazda 3 with 2.3L engine. i'm contacting hypertech to request a product for the 04 model, mine's an 04 3. but this might get you close to that 20hp ur looking at.

also i'd reccomend a catback exhaust system. it sounds way better and gives a bit of hp.

here's the website for that power programmer if ur interested: http://www.corksport.com/hypertech-m...rogrammer.html
