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 .
Unleash the ECOBEAST
If you want to get better gas mileage and more horsepower then look no further. This thing will make the monster come out in your ECOBEAST. This is the best thing since sliced bread. I have tried the economy and the performance levels and gained 3 miles to the gallon. It's super easy installation and make sure you update it prior to installing.
