Reviewed By Jake B (VERNON, VT) Reviewed for a 2016 GMC Sierra —7/20/2017 4:20 AM

Was hesitant at first because its almost 200 bucks but it works like a charm. Leave it plugged in all the time the light goes out when i turn my truck off, other reviews i read people were saying the light is always on. Love having more power however i do get couple miles less per gallon but if im driving far its as simple as reaching down and unplugging it.

Works great

Reviewed By Kevan C (Hagerstown, MD) Reviewed for a 2012 GMC Sierra —7/5/2017 2:02 PM

Bought a pre-owned Sierra 1500 with the Vortec 6200 where the previous "computer" calculated MPG was 10.2 average. I cleared the computer, installed the MPG default tune with firm shift. With 2 tanks of regular 87 octane I now get overall "computer" average of 16.7. I will hand calculate at next fill-up.

Hypertech Max Energy 2.0 Programmer Reviews


Reviewed By George C (ROANOKE RAPIDS, NC) Reviewed for a 2014 GMC Sierra —5/24/2017 7:40 AM

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 .
