You're better of getting a dyno-tune done instead. If you don't have a dyno-tuning joint anywhere near, find a tuner, wideband O2, and someone with experience to help you tune on the street. Those off-the-shelf tunes will help you get close to what mods you have, but a custom tune is where it's at!
