Hypertech Max Energy Programmer
I purchased this for use on my 2008 Mustang GT. I had to download a newer version of software from the Hypertech website before I could install it but that was quix and easy. Once installed I was pleased with the new level of performance that it provided on this vehicle. I installed it after installing a K&N Cold Air Intake system and Gibson exhaust system. This unit tied everything together and the sum total of performance gains was quite impressive, great tuner.
