okay im trying to order an online tune from vmp (the $129 one custom email tune for all fords) the only question I don't know what it means is "add tune files?" so is this an addition file on top of the first one or what? and what is the first one im getting? is it just a mild tune or what? The options to the question are "add one gas file or nitrous" "add two gas files" "add a race file and specify what octane" can anyone tell me what each option is for what makes the race tune different from the other gas tunes? is the first tune im paying for a gas tune?
Blacking it out, MAC duel exhaust, SR CAI, Performance Automatic shift kit. And a long build list wrecked in July '14
