Hypertech Max Energy Programmer Experiance
First of all I was impressed with how quick it arrived, the experience in using it!I after installing it and driving it I was totally impressed with the acceleration especially from 20 mph onward, the truck acted like it had a blower on it, and when I hooked up my toyhauler which was the main reason for getting the chip, I was very impressed by how it seemed like my truck doesn't have to work as hard pulling,didn't help mileage empty or pulling I have 01 GMC 6.0 200600
Very easy to install and works great. I had been very unhappy with my overall mpg with my gas fueled truck since purchasing as I have been getting 11 mpg at best (driving down highway with no load). When towing a trailer my mpg's dropped to around 7 to 8 mpg. Since the installation of the Bully Dog GT I have seen increases of 3 to 4 mpg across the board. That is an amazing 30% or better increase in fuel mileage. I just averaged 15 mpg running down the highway at 70+ mph which is almost a 40% increase! This increase in mileage will make for a quick payback of my initial cost of purchase. I can't really attest to increases in horsepower however I'm sure their was. I really didn't have a problem before getting the Bully Dog as I was most interested in increasing fuel economy. My truck does shift a little harder since the program download but this isn't a detrimental observation. I thought that the driving coach would be kind of silly but I have found it becoming a challenge to beat. It has helped my keep my foot out of the gas quite a bit. I had to turn the "chiping" off as that became quite obnoxious but it was a simple change to make. One of the minor complaints that I have is that I would like to see a little bigger screen. I'm a little older, okay I'm old as my son keeps telling me, and wear bifocals. So, I find it hard to read the very fine print on the screen. However, the gauges can be seen during normal operation. For future purchasers I would recommend getting the optional windshield mount. The mount that comes with the GT is okay however I find it to vibrate a bit while driving. The optional windshield mount appears to be of a more stable platform which I will most likely be purchasing in the future. Overall, I'll never own a truck without a Bully Dog GT. This is probably the best aftermarket item that you can add to your truck.
