If you want to check out the world challege protege specifications then here is a link i found www.speedvisionwc.com/competitors/vts/02-mazda-protege-2.0.pdf
I was wandering if I could get a full N/A tune and the after about maybe 200whp I would put a turbo or a supercharger on. Whould that be possible because i want to get maximin Horse power from my Protege 5, the only mods so far are a Injen CAI.
