Ground wire mod

Has anybody here heard of this mod? I was checking out the MoparTalk forums, and saw this mod. Apparently all it takes is a 12 gauge wire with an eyelet on both ends. It attaches at one end to the throttle body on one of the attaching bolts, and the other end attaches to a ground on the inner fender well, preferably on the battery ground screw. It is supposed to at least minimize the throttle lag, as well as make the tranny shift more crisp.:4-dontknow:
