because thats just on idle with out any darin like light/s fans etc, i have seen the voltage drop to 12.5 n the bat light flicker!
also low voltage aint good when hard on boost, the fuel pump dont like it!
have a read of stus articals

Dose it go below 12v? if it has 12v its fine what dose it have at the fuel pump when u switch a few things on. If its a 12v fuel pump and a 12v ecu then 12v is all it needs! And when u say it drops when u turn things on dose it rise when u rev it?
