I have not installed a BAP on a c6 yet but the c5 cars it goes in the engine bay under the fuse box and works great. The c5 vettes have twin pumps from the factory and use a good sized wire, unlike the 20+ year old Mitsubishi technology.

You are not changing the fuel pumps or wire so resistance (ohms) stays the same and as you increase voltage you are going to make the fuel pump spin faster, as load in the pump increases it will draw more amps. So if you are using more fuel then the pump can supply you loose fuel pressure, by upping the volts and fuel pump rpm you get more fuel but if your fuel pressure does not go up a ton the fuel pump draw should be about the same.

I would look at instructions for a magnasen (spelling?) Super charger on your car and if they use a BAP fallow there instruction.
