How much do they cost for the 4.6 2v GT? You only plug it in and reprogram the ECU once, right? So pretty much, its one time use and everything is set? Because I'd like to get gears, and if I have a friend with a hypertech programmer for a 99+ GT, could I just borrow his to recalibrate my car for 4.10s? Thanks!
EDIT: Their site says 99-01 4.6 mustangs. Why not 02-04? Will it still work?
