William M from Clinton, MO said, "unbeliveable power difference. tranny shifted 10 times better. easy to install, did mine in less than 30 minutes.only complaints is the switch is a little on the flimsy side and when on the 80 horse setting its real doggy untill you stand in to it and make come to life. overall very happy, its unreal how much these trucks are de-tunned from the factory."
