I believe the LPR had a Pro Charger which was installed by Hennessey before they started using Roush Chargers
It was originally sent to Hennessey for the Procharger when it did it's original 2011 SEMA, then when Hennessey switched to Roush last year, he switched to Roush as well for SEMA 2012. Last I heard, Roush was still the supercharger on that truck. I'm not sure if it was installed by Hennessey or not.
