Ok I don't know when this started, somewhere in the last 6 months as I have not made any changes to the 04 silverado till last week.
When I try high speed ( as i have in the past) it fails, either times out or fails toerase when doing a flash calibration only. Works OK if I uncheck the highspeed block.

Did you change out the stereo system from factory since your last tune? If so that could be it. I've had enless headaches from aftermarket stereos (and alarms!).

HP can't fix this. It's a problem with the Sirius receiver not shutting up when it's told to. Pull the radio fuse before you flash and all should be good.
