lookin to buy a duramax.
i would dtay away from the edge products they have caused alot of problems. the best is efi and if you get a 05 or older then you can get a dsp5 or dsp2 switch. that will allow you to run 5 or 2 different tunes
why do you say this? has this happened to you at all. what modules act out in the truck.
