i was thinking the other day if there was one out there or if u could make a comp box or flip a switch that puts a resister in the pump wire to reduces the voltage going to the pump. The reason being, is that when u run huge injectors, even with the box off the truck still smokes. I have dd 2's and it smokes a little, i can't imagine running BD v's and not getting pulled over in the good ole state of California. Just a thought, maybe somebody has tried this or has been thinking of the same idea, ... . thanx, reb
