I purchased a different controller at a higher price. It caused the check engine light to come on and it surged when idling. I spent (6) 20 minute unsuccessful attempts to talk to their customer service without any success. I ordered the Hypertech. Everything was programmed in 10 minutes with the Hypertech. I've owned another Hypertech unit for 8-10 years and it still works perfect. I don't know why I didn't get Hypertech first. I love my Hypertech and so does my truck.

Absolutely amazing investment. I couldn't ask for more. This thing can change just about everything in the vehicle, and has the ability to be custom tuned. Couldn't ask for more. I will be getting a custom tune from Lew soon, highly recommended product!
