does anyone have a GTECH PRO SS ? if so how do you like it? i seen in the june issue of diesel power where they tested it on low horsepower vehicles with good results. i thought this would be good for me being its not that easy to get on a dyno around here. and i would think i would be able to verify my horespower increase with any mod i made when ever i wanted to. if anyone has one on a high hosepower cummins and found it to be accurate please chime in. i know its only going to be accurate if you enter the exact weight. thanks in advance REALTRUCK
