I have an '03 and a couple of months ago got the new programming updates done from my dealer that has improved the gas mileage, etc.
Other members here had the same thing done and found out that they could no longer use their Diablosport Predator Programmer.
I contacted Diablosport and they had me download the stock tune from my truck onto the tuner, then upload the stock tune to my computer so I could email the tune to them so that they could look at it and fix it so that I could again use my programmer.
They sent the programming back in less than a day and I am going to "play" with the settings to see if I can get more out of the engine. The main thing I wanted to have back was the shift control being removed.
