This package is for 2001-2010 Duramax trucks only. It includes 5 custom tunes for a DSP5 switch so that you can switch between tunes while driving. Our tunes are economy, tow (w/ turbo braking), street, hot and race. Please specify in the stated area if you want any other specific tunes.
*PPEI does NOT build smoke/lope tunes*
The tune will be sent via email, and you will need an EFILive V2 or AutoCal to load the tunes into your vehicle.
