best bang for your buck

Easy to install. Can tell the difference before and after. Just haven't been able to keep my foot out of it long enough to see about better gas mileage. Would recommend this to anyone.

Hypertech Max Energy Programmer Reviews


Great product!!!

Reviewed By Matthew B (Ames, IA) Reviewed for a 2004 Ford Mustang —3/10/2015 4:56 AM

I bought the programmer to recalibrate my speedometer. The previous owner swapped gears to 3.73 and didn't bother correcting the issue himself. I researched a few different options for calibrating the speedo and Hypertech's Max Energy Programmmer was the best option. The tuner was very easy to use. The only downside is the soft ware update. Immediatly after unboxing the product it requires about 25 minutes of installation and updating with a PC. I expected plug and play.
