I have a 2000 Ford F-250 with the 7.3 in it, it has a tymar intake, straight pipe, and a superchips tuner on it.. I have heard that you can stack chips and put programs into the computer for the fuel pump to gain crazy horsepower, but i have no idea what to do. I am thinkin about gettin a DP Tuner on the truck and gettin rid of the superchip cause it SUCKS, but wanted to see if i could stack something with the DP Tuner? I will also be gettin the 4 pod mounted gauges soon so i will know what is going on and not blow **** up. Thanks for the input.
