Well, I just installed my ground wires. I just got 4 gauge wire from a local shop and grounded all the points listed in the tech forum. I felt a little improvment, especially 2nd(I have an auto, 2nd is sluggish) and I have a big stereo, and the lights didnt seem to dim at all when it hit hard, so if no power was gained, atleast I can see better at night Despite all the contraversy behind these, I think they did improve my acceleration a little, I feel a little more power. I would suggest this to anyone who is bored, and wants a cheap improvment/mod.
