I have a Chevy 3500 8.1 with the Allison Transmission. Done alot of research and finally decided on the Superchips Flashpaq tuner. I pull a 24 ft Titan (steel) trailer loaded with about 14,000 lbs. Prior to the tuner I was gettin 9mpg pulling......I have since jumped to little over 13mpg and the additional power is very noticeable. I tested each of the programs "Economy", "Tow" and "Performance" and let me tell ya I wont be in the "Performance" mode very often as the power produced was intimidating.....from a dead stop it just simply boiled the tires and at 120 mph there was plenty of pedal and plenty of power still available. Definately worth the money!!!! Easy to program and after doing it a couple of times it now only takes 3-4 minutes to program another mode. Great investment and my hats off to you guys!!!!!!!!!!!!
