I have been seeking the internet to determine the best tuner for the 07 Mustang GT, unfortunately it seems the advice you get is usually from the dealer selling it, which proves nothing.
Id like to know what you all recommend with regard to tuners.
I have a stock, 5 speed GT.
Im between Diablo and SCT and from what Ive learned the SCT only is an advantage to Automatics.
Seems the Diablo has a horsepower increase from 279 to 293 with a cold air intake couldnt find anything on the SCT.
Are there any tuners that allow multiple car tunes? Lets say it does my Ford and my GM?
