This mod is for real, it's not BS. With that said, the gains that some are advertising are definitely overblown. Go to i-club.com and search their forums for grounding mod. You can do this mod yourself without buying a kit. HKS sells the kit for like $150! You can make your own kit with less than 1/4 that. Someone on i-club.com posted on how to make your own grounding kit with high quality wire and connectors.
