Does the job as advertised. Recently lifted my jeep and put 31" tires on. Prior to installing the calibrator, the speedometer was off 7 mph. When reading 55 on speedometer, GPS showed me going 62. After calibrator installed, speedometer is dead on with GPS speed tracking. Would definitely recommend and may upgrade to the max energy software.

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 .
