I have a Predator U7185 I believe, for my GMC 2005 LLY. It works nice. I have used all the tunes except the 100HP. Just don't want to destroy my tranny. The tuner allows you to adjust for tire size. That's why I bought it fore most. The tunes second. Scanning ability third. The biggest complaint for me is that it screws up your mileage computer on the DIC. Mine is off by approx. 1/3. Says I'm getting 21MPG, when I check it with a calculator it might be only 14 or 15 MPG! If they could fix that I would give it 5 out of 5.
