For those of you that have installed a tune using Hypertech or similar device...did you have to remove fuses to satellite radio, remote start, etc before installing the tune? How important is it to do this? I will be using a Hypertech Speedometer Calibrator.6
Update: heard from a Hypertech tech that unless you have aftermarket items installed you no longer have to remove any fuses before using their product. He said the instructions I found online are old and need to be updated.
