I bought a used 1.7L KB for my '03GT and want to get a mail order tune to drive it to the dyno, about 30 mintues away. Anybody have any good experience with a mail order tune for a Predator, because I already have a predator. I know MPH and Brenspeed and some others but they have Xcal.
Or do you think I would be OK to back off the timing, add some fuel and just watch the Wideband while I drive it nice and easy to the tuner?
