I had a Edge Evolution CS as stated above and it produced a fair amount of power for something that was supposed to be a 120hp tune. My friend has a 05' and we figured we would swap for a few days and the minutes we installed the Diablo on my truck, it was a WHOLE DIFFERENT ANIMAL!!!! :sofa" So we raced...I waxed his @$$ and he used to wax me. Both are almost identical as far as mods. I have 190,xxx he has 101,xxx and my truck has a few sticky injectors and a bad ICP sensor. I figure one these problems are fixed (October 13th) I will be faster due to a "perfect" running truck. The thing that shocks me is the Diablo says its a 100hp tune but it runs like twice that haha, or atleast it feels like it. Can anyone give me an explanation? David says his truck runs a bit better with my edge than the Diablo in his truck but the Diablo completley changed my truck. Any advice?
