Went from Stock to 35s. Really easy to put on, truck shifts smoother, speed is perfectly on with two GPS and I also had my wife drive her car next to me and tell me how fast she was going. I actually gained 1.5 MPG, don't know how or why but it did. Tucks right behind the dash and I left the usb in it so I could change it if need be without taking the dash apart again

Glad I bought it. Truck runs great an a bit faster. Dose not do a few things it says it dose. Depends on model of truck. But overall it works good
