Traded up from a Cobalt SS/TC to a 2011 Mustang 5.0. I guess I assumed this car would be supported by HP Tuners. From what I have seen by searching its not supported yet. If it helps I live in the Chicago area and may be able to drop my car off with the HP Tuner guys for a few days. Anyone have any experience with the handheld tuners available for the mustang? I would much rather use HP Tuners but oh well. Love this car I cant wait for even more power.
