On any of the Forums I vist the topic of Programmers and Chips come up all the time. Most agree you can get more pull power, but they all pretty much agree that Fuel mileage doesn't change or if they claim it does, it's only 1/2 to maybe 1 MPG. My GM has plenty of power so I'm not about to upset the apple cart.
