I have a tuner for an 05 lly duramax and I had it set on your 100hp tune when I had my stock radio in, I took it to an audio shop and had them out in a different radio and then a few days later I went to change my tune and it said script read failure and locked up my pcm but I managed to figure out how to restore it and I tried re installing and it failed again. I am wondering what I need to do to have it install properly. Thanks!

that will need to be disconnected too.. anything aftermarket/dealer installed...

you can try just pulling the fuses first.. if that doesn't work, then you'll need to disconnect 'em...
