This product enables you to switch between 5 tunes on the fly on 2006 to 2007 5.9L Cummins Trucks and 2007.5 to 2015 6.7L Cummins Trucks.

 These CSP5 Switches are connected via OBDII. The switches utilize a pass-through OBDII so you can hook other electronics up to your OBDII and have your CSP5 switch functioning at the same time.

 **Please note: You need the proper tuning to make this option available.**
