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.
2014 GMC OIL SAVER
I bought the Max 2.0 because other reviews had said their trucks had stopped using oil when the 4cyl program had been turned off. I have run this program now for close to a thousand miles and haven't used any oil with the engine running on 8 cyl all the time. Gas mileage has remained about the same as before, I haven't noticed any problems with the Max 2.0 programmer. My 2014 GMC sierra has a lot more horse power running this programmer .
