I like this programmer a lot. Could see the difference in power on my Sierra. Would recommend to friends and family.

Up to 9 gauges at once and easy to use. Best part is you can check your check engine lights and clear the codes. And has a good maintenance reminder on all a wide variety of maintenance for your truck. The only thing I am not sure about is unplugging and replugging it in if it saves your data.

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.
