Really the Power Pkg GT, Bullitt and Mach1 should be almost identical. The question is can FP add in a bit more power due to not having to SELL the car with the tune, since it doesn't have MPG goals to hit.I don't think there would be too much of a difference between the GT and GT performance package 1, nor between the M1 and Bullitt, at least in stock form.
