Does anyone have one of these chips? How do they work or compare to other high power chips, TST Comp or others? What is the price range I have seen them as high as 1300 and as low as 750ish?? I currently have the TST Comp, Duramaximizer, and a predator that I used for speedo adjustments, but has a 120hp tune on it.. what would give me the best power and say 1/4 mile times? I am hoping to get my Ext cab SB 4wd with hummer tires to low 13's I do have the transgo, TCC Valve, Converter and deep pan.
