UpRev Engine Management Solutions

What kind of mods are you trying to tune for? Uprev is a pretty powerful reflash program that is very capable in the right hands. Stand alone is not necessary unless your talking about some crazy build that's over 500whp. Not that it's not possible to tune that with it uprev. It's just at that point you will want a engine management that's designed for such a task. Something more than a reflash program that's limited by the original tables. The stock ECM once calibrated properly works very well but of course has it's limitations. The ecm was intended for a use as a family car. Not a 5-600 whp race car lol.
