custom tune for 04 silverado

It doesnt work for any of the canned tunes now either. It says the same thing every time. I followed all the instructions so idk what happened. it worked fine before I sent all the tune files to my computer

sounds like there's an issue with the predator itself... cuz if it won't do anything with even the canned preset tunes, then it's not a tune issue... something's up with the tool itself...

so how do we fix that? I dont want to be stuck on the tune my truck is on right now forever. Ive never had a problem with it before its always worked fine for me

so the problem was my aftermarket stereo. Unhooked it and the tune loaded fine.
I appreciate the help

man, I would have suggested that, but usually that is an issue with canned or custom...interesting.

glad to hear it is working
