So I'm trying to get better mileage out of my 96 lesabre and I'm thinking about upgrading some of the wiring to up the mpgs. I've already installed 2 gauge wiring from the alternator to the battery, engine block to the negative of the battery and the negative to chassis and it seems to have helped and now I want to rewire to fuel pump to up the pressure and help the fuel atomize the fuel better. zzp says that the stock 18 gauge wiring looses 1.5-2 volts by the time it reaches the pump. The car is wired for subs and I would like to add a distribution block off that and use the stock wiring to activate a relay think it will help? Also zzp sells a alternator voltage booster that ups it by 1.2 volts that I think might help too
