(Competition Tuning - Fully Built Trucks)
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 on the fly. Our tunes will be built to the specs of your fully built truck (built motor, turbo(s), injectors, dual CP3's, etc). Please specify your mods of your truck and tunes you would like in the stated areas below.
