i just bought an HKS VPC from japan a few months ago per my buddies advise, and now im not needing it... first 450$ takes it. the VPC is complete with harness, controler, intake air temp sensor, and the map sensor. there is probebly a few other parts that it includes that im just not remebering right now. ive only had it out of the box once to look at it. it was used when i bought it. so the actual working condition was gauranteed by the people i bought it from. I HAVE NOT USED IT madtdogs@aol.com for ?'s thanks Terre
