Give up 2 years of warranty for 30-40 hp. The car is powerful enough for the track.
Track key doesn't add any power
Not sure about the warranty thou
It actually does.
Its not advertised to add power, but if you go on mustang forums many owners have done before and after dynos and it does in fact add about 30 hp.
Warranty is reduced to 3yr instead of the typical 5yr.( only if ford believe the problem was caused by the tune)
