So i got my gears all done, I put 3.73's in and i love them. I have a diablo sport that I use to gain a little more power. when I went to change my gear ratio over on the diablo so my speedo would be right it started then said that the tune did not finish loading and i must reload the original tune and it gives me 3 choices.

one is no and i when i choose it, the tuner just says unplug diablo now.

another is yes and it starts to load the tune but just restarts the diablo

and the last is force and that says this is a dealer choice do you want to do this, so i dont choose that cause i dont want to mess anything up.

If anyone knows anything about the diablo sport tuners or if you have had this problem before and know how to fix it i will be really happy i want my speedo to be corect so i dont get any tickets at all.

I had a Diablo when I had my old 98 V6, and I never had that problem. It's probably sometype of weird software issue. Did you buy it used, if so, did they unlock the tuner? If you bought it new, call Diablo and get some tech support, they may have screwed up when programming the thing.
