I have a ProSport Premium Boost Gauge for sale. I bought it with the intention of installing it and changed my mind. I shaved the feet off the mounting cup, but nothing else has been changed/installed and everything that came with the gauge from the factory is included. It's been sitting on my shelf for a year now, so it's time to let it go. You can learn more about the gauge here: http://www.iagperformance.com/Prospo...270-pk-psi.htm.
$50 shipped to anywhere in the lower 48. PM me if you're interested.
