Purchased the rebuild service for both SuperChargers on my 2011 230 Challenger. Shipped both on 5/17/17 via USPS. Had an issue with USPS and was getting a little nervous as the tracking information at this moment still shows that PWC Muscle hasn't picked them up. Anyway, communication with PWCMuscle was easy...spoke to Joe on Monday, and even though USPS isn't updated, PWCMuscle picked up the superchargers, turned them around the same day, and I received them in the mail today!!!! Great work guys, I appreciate it and am getting ready to install and be on the water for Memorial Weekend. Steve
