Always better to reprogram instead of tricking the computer.

The Jet Performance Stage 2 Module does what it says it does! You can hear the difference it makes in the spark and fuel timing curves. The power is noticable. I am using it with a cold air intake, high flow exhaust, and a TB spacer. The combination works as advertised.

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 .
