Works just as described, just plug in and go.

This was possibly the best thing I've gotten for my truck. I just dropped a new engine in it June 2016 due to the oil consumption issue being so bad. So, I wanted to try and protect this one best I could. The truck drives and shifts much smoother now always being a V8. Highly recommend for anyone on the fence of ordering one.

Edge Evolution Programmer Reviews


You can feel a difference

Reviewed By Bobby S (Bulverde, TX) Reviewed for a 2008 GMC Sierra —1/13/2017 5:56 AM

Easy to install and you can certainly feel a difference in torque/power. Easy to install and the extra gauges are neat. The only issue I am having is that when on the highest setting and I run wide open it makes my truck ping a little. I'm gonna run a few more tanks of premium fuel through the truck then investigate further. I will purchase this product again for my future vehicles.

Hypertech Max Energy Programmer Reviews


Hyper Fast.

Reviewed By Jeffrey F (Schenectady, NY) Reviewed for a 2008 GMC Sierra —8/28/2014 12:54 PM

Fast shipping. Excellent value. Only issue I had was having to update the programmer new out of the box? Otherwise easy install. Using the econ setting so I don't necessarily feel a performance gain but hoping for better fuel mileage. Only programmer I use is Hypertech.
