code help on 6.0

i dont have the code number but the code reads high boost on circuit a. It only happens when my edge turns off all of a sudden i guess cause of heat and i guess i gun it in stock.

thanks

well the code is going to return more then likely when you run it stock, and the code is probably what is turning your edge tuner off. It is more then likly high voltages on circuit A(related to the turbo charger). Which could indicated a bad solenoid(mounted on your turbo), bad wiring(wiring shorted between each other, the pcm request the solenoid to do move and it expects to see the correct amount of voltage and if it sees to much or to little it will set a code), or a bad PCM(highly unlikely). If it is a high voltage code. Hope this helps, the code would really be helpful I could lead you down a better path.
