Great programmer for the Sierra/Silverado trucks. I was having issues towing my trailer up steep hills. This did the trick. I don't like the idea of having to use 91 octane fuel all of the time now, but it does give it the extra boost and the shift points are much better than stock. However, it does shift hard and stays in gear much longer than the stock tow haul mode. I will probably mess with the manual programming over time, but the factory modes work great. Performance mode is fun, but make sure you have a full tank of 91 and not mixed. Mine pinged so I went back to the 87 mode until I ran that tank through and filled up with 91 again. This time no pinging. I was able to run the tow mode with mixed fuel, just not performance mode.
