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.
