REGEN is the burning of soot built up in a DPF. 

 The Emissions Equipment for diesel trucks has changed quite a bit through out the years. In 2004.5 all heavy duty diesel pickups had to install EGR's which is the exhaust gas recirculation system. Basically it turns exhaust into inert gas and directs the gas back into the combustion process. Then in 2007.5 the EPA required pickups to use a DPF. The DPF, or Diesel Particulate Filter, is a filter that catches soot, or unburnt fuel from the exhaust. Once the soot builds up, the exhaust heats up to burn the soot off. Starting in 2011 Diesel Exhaust Fluid is used to treat NOx emissions, in addition to the EGR and DPF treating the carbon emissions. 

The DPF is a crucile part of treating diesel emissions and each OEM utilizes and operates their DPF a little differently. Below, the DPF in the 2011-2016 LML Duramax is explained.

Did you know there is no reason to delete the emissions from your 2011-2016 Duramax? 

DuramaxTuner.com's SPADE is capable of adding up to 135HP to your EMISSIONS INTACT LML. 

Actually, more and more people are tuning their 2011 + Duramax (LML) with the emissions equipment intact.  This is a great option for Duramax owners that would like a nice, quiet, reliable, efficient truck that performs well every time. However, many LML Owners have some basic questions prior to pursining emissions intact tuning. 

• The LLY Duramax  is a great truck from the factory for there are 3 modifications every owner should make! The LLY was manufactured 2004.5 and 2005. There are a few 2006 models that are labeled as an LLY, however they have all of the LBZ upgrades from the factory, so for performance applications consider those an LBZ. An LLY was the first Duramax with the injectors outside of the heads, a variable vane turbo and a 50 state EGR.
