I bought a used ProCharger D1 and got a little screwed with missing a pulley that was supposed to be included and the guy used his own inlet elbow that ended up failing. I ended up having to buy a few minor parts from PC to complete the install. Still got a pretty solid deal on it though. It was shipped to me instead of doing it in person. I would do it again but ONLY if I'm meeting in person. They guy stopped returning texts and calls after the sale. Meet them in person to take the parts so you can check everything out.
