I have a Predator that has been used a couple times to download tunes from Mile High Dyno. You can get a tune for whatever on it or use one of the existing tunes for a 2.93, intake, exhaust car. My car dyno'd 455/477 with this tune and A/F was spot on. $180 + shipping. Pm me with any questions or call me at anytime, (850)240-4614. Thanks, Eric...:beer:
