Duramax Performance Modules

Diesel Modules performance modules for the Duramax family give Chevy and GMC diesel owners more usable power in the driving zone, quicker turbo spool and a cure for dead pedal, without reflashing the ECM. Each module plugs in between factory sensors using OEM-style connectors. Stock settings are never deleted or modified.

The collection runs from the original 6.6L LB7 (2001-2004) through the LBZ, LLY and LMM (2004.5-2010), the LML (2011-2016) and the current L5P in the Silverado and Sierra 2500HD and 3500HD. It also includes modules for the 3.0L LM2 and LZ0 in the Silverado and Sierra 1500 and the 2.8L LWN in the Colorado and Canyon. Every listing names the engine code and model years it fits, so check your engine code (on the emissions label under the hood or in your owner's manual) before you order.

Driving a Silverado 4500HD/5500HD or a Duramax-powered motorhome? Those modules are in the Medium-Duty & RV collection. If you are unsure which listing is yours, use the Year / Engine search at the top of the page, or call or text us with your year and engine, and we will point you to the right part.
