2006-2007 LBZ Duramax EFI Live Tuning

Note:

•  These are files only! You need an EFILive AutoCal Device to flash these tunes onto any trucks!
• We REQUIRE a stock read file for all Cab & Chassis, Topkick/Kodiak, Van, and LB7 Models.

Unlike most files on the market, Diesel DNA is true custom tuning for your Duramax. Just let us know what you're doing with the truck and we will get you tuning that is written specifically for your truck and your usage.

Diesel DNA writes their custom tunes for the Duramax and is highly regarded as one of the best custom tuners for the Duramax engine. Allow you to make safe and reliable power in your 2001-2010 Duramax.

We do not support lope tunes or smoke tunes.
