I just got my brand new out of the diablo predator today from Xtreme Diesel Performance. I read the directions that came with it and plugged it in the truck. When i click on the performance tune you know it says to turn the key on but do not start and also set the parking brake. I do all of that and then it says my calibration is not supported. What is wrong or what am i doing wrong?

OK, it should allow you to upload a copy of the stock tune and post it here.

I got it fixed i took it my chevrolet dealership and they reflashed the computer and turns out it had an update out for it. It works great now and i have it on the 65hp tune and i can really tell a difference. Thanks for helping me
