on rmpoutlet.com they have somthing called the Stage II HO kit....heres the link to the kits. http://rpmoutlet.com/musv6ati.htm ..... is this basicly the tuner kit with a smaller pully. Im asking this because its priced more then the tuner kit and has every thing you need for the kit, unlike the tuner kit. It also says it can run 11psi.thanks
