Ive Got An 04 Slverado 1500 Z71 With A 5.3. And I Was Thinking Of Putting One Of Those Hyper Ground Force Wiring Kits They Say It Gives U Better Gas Milege, And Horsepower. I Was Just Wondering If Any One Had Heard Or Used One Of These Systems Before. Thanks For The Help And Comments Ahead Of Time.

 

Don't believe that some ground wires will give you better gas mileage and more horsepower. If that was so I would have notice some change since I am running a 4/0 welding for my positive and ground wire, 2 gauge from the alternator to the battery, and 2 gauge from the battery to the fuse box. The only difference I have notice is the truck starts a lot easier.
