im about to buy a mustang gt with a vortech v2 and i he told me he had the ecu flashed by apex a wile back and his battery died and he lost all of his fuel maps and he has a preditor tuner but cant install it intill it gets flashed to stock my question is how much does the flash cost from ford? Is the diablo capible of tuning a supercharged car with ported plenum tb intake and heads? Can i take the car to a dyno and have them tune with the preditor? Is it possible to get a new tune loaded on the preditor? One more thing how much timing would you bump down to run from 91 octane to 87? I barly ever floor it and i could use 87 when i just want to cruise.
