I bought one of these off Amazon, from an unauthorized seller - no warranty, and probably outdated stock. Returned it and bought one from AA - fresh updates, manufacturer warranty, and it was $30 cheaper than the Amazon one. The device works great, 4 cyl mode has never kicked in, the engine is a Jasper reman and hopefully will never have the oil burning, failing internals , etc that AFM causes in the 5.3l engine

Very easy to use. Fixed speedometer error. Can tell the difference in performance

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 .
