Talk about bang for your buck, WOW. Pretty easy to use and the set up was a breeze.

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 .

Used on my 2005 Excursion with 37's and now my speedometer is spot on.
