No answer on the tune forum so let me ask here
Is it necessary to pull the radio,amp,acc, and Onstar fuses when doing the tune with the Predator on a 2006 C6 6sp
I have never done it on mine and not had an issue. However they would not put it in the book if there was not a possibility there cold be one. So do it at your own risk.
When I first got my Predator, I pulled the radio fuse to install the tune and the radio died for a couple of days. I ended up pulling and reinstalling the fuse and now it works fine.
Since then, I have loaded several tunes and made adjustments without pulling the radio fuse and it has worked great. Just make sure you turn off the radio and the A/C system before loading a tune. Also, make sure you put the car in the on mode (vs acc mode) by holding down the acc for 10 seconds.
