The Diablo I3 is a waste of money. You would be miles ahead buying a HPTuner. If you use the Diablo to disable DOD, your truck will run like crap because your fuel composition will get thrown into a constant positive loop because of the virtual sensor. It will also beat the crap out of your converter because the settings are crazy. With the HPTuner, you can disable the DOD, E85 and program the converter to not slip in 1-4 gears and then allow it to be in 5 & 6 for fuel economy. If you're going to drop the money, drop it into a real tuner with limitless editing to ecm and tcm. I bought a Diablo and constantly had to reset my fuel composition with my bi-directional scan tool to reset fuel compasition due to the faulty positive feedback loop because of gm cheaping out with a "virtual" sensor. It would literally last a day and be right back into misjudging the composition causing the truck to run far too rich. The HPTuner also works as a scan tool.
