I kinda screwed up...... I bought the kit minus the Diablo Sport tuner because I already had an SCT and the guy said it would work fine. Well, I found out that I would get just a start up only tune and then I would have to take it somewhere to get a "real" tune blah, blah,blah....so I just decided to go ahead and buy the Diablo Sport and sell the SCT, that way it was plug and play basically. SO, the reason I told you is because they knocked $400 off the kit price but the Diablo cost me $600 from Paxton with the tune.
2006 Mustang GT Paxton H.O. kit POLISHED:
$4200 + the $400 they knocked off = $4600 and then the little things...some tools, oil and filter, gauges, etc... I've got $5000 in the whole job.
