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 .
Worked just like it should have, I got all parts before I was supposed to which really helped. I will be using auto anything for things I expect to purchase in the future. Tuner works as advertised, got about 6mpg more after installing the GT platinum. Which is weird because the truck is so much more responsive and has way more power. Truck was always hard to start since installing the unit it starts first time every time. Not sure how it fixed problem but I like it!
