ok, so i have my svr now, has ghost also tracker fitted.

Have been told the pandora storm has this function, has tag etc...., I can only use it to physically cut a circuit somewhere(can't can bus as will interfere with ghost). My questions are, will cutting say, the fuel pump while in motion flag up an unclearable fault, cause the engine to run lean until said fuel in lines runs dry,or will drop in fuel pressure stop ignition. Are there better ways to stop engine, ecu somewhere, again could bring up faults/damage circuits. Lastly, how reliable is the storm, don't want the thing glitching when i'm doing 70 down the motorway.
