After receiving the tuner, I updated through "ignition". Plugged in to my port, and could only get 12% download from stock settings. Called Superchips, got 5 more updates, had to unplug 2 radio fuses,and worked great. 3 to 4 mpg better on economy setting without losing power. Am going to try towing mode, and hope for good results as well. Good product, very good customer support!
Very simple product with great results
This chip is very simple to use and I have been impressed with the performance it offers, I noticed a big difference when it the truck switches from 4-8 cylinder (not so much lag) and it definitely increased the overall power. I cannot comment on fuel saving since I originally bought this since I was doing a lot more city driving than before but it seems I'm getting about 1MPG better on roads under construction and morning traffic. Overall couldnt be happier
