anybody know if ground wiring your engine really does anything or not, i saw it on dsmtuners, but for some reason i cant post there so ill ask here. supposedly helps with idle, acceleration, and starting, apparently just helps the car run better over all, anybody know, thanx.

 

so i installed the kit, i didnt get to the alt. or coil so im not sure about the whole thing yet, but it does seem to help my top end a little, and there is def more response when i punch it from about 3500 on up, doesnt seem to help low end though, but i dont know if its cause i didnt get to finish the install or not. worth the 40 bucks and the time, still not sure, but im thinking yea, probly is.
