The Mustang Supercharger Single Belt Phase 1-2 Upgrade belongs to a line of ROUSH Mustang supercharger kits designed to allow for easy upgrading.
The idea behind this line is that customers can buy in at one phase in the line and upgrade later while reusing as many parts as possible from the kit that they already have. This upgrade kit includes the components necessary to do just this.
This kit includes the following:
This part now utilizes the ROUSH Flash Voucher card to be calibrated using ROUSH Diagnostic Tool (RDT) software and pass-thru device. If you do not have access to an approved pass-thru device, you can send your PCM back to ROUSH to be flashed for an additional $100.00 fee.
