Right now Tracy is the only selling them. I'm not sure how many he has in stock. They are a PITA to install and you will throw some codes because of the VERY HIGH pressure at idle, but you can get around it with the tune. Going to need a larger diameter intake tube if you are going for 425+ (auto) because we are maxing out the MAF at that point on my car. There are some bandaids for this, but they could be dangerous.
