I bought this to fix the Speedo on my truck since I lifted it. It worked great and did what I wanted gave it some power and woke up the truck a little bit. I'm very happy with it.

I purchased this programmer along with a K&N FIPK Air Intake and my truck is like a rocket! Huge difference in power. I'm trying to lay off the gas so I can check my mileage, but havent't been able to yet!!!
