Best deal I could find for this product. Product performs great and I couldn't love it any more.

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.

This product works just as advertised.. I will be ordering from you again soon!!! Delivery was fast!! We almost traded our new truck in because of poor performance caused by active fuel management.. The truck now stays in V8 like it should!!!!!!!
