*** IMPORTANT ORDER DETAILS ***
Custom tuning is required
3.0L Duramax Throttle Valve Delete (LM2)
The 3.0L Duramax LM2 throttle valve delete removes the largest restriction in the factory intake system to improve airflow and reliability. The factory throttle valve features a 2” inlet and an internal throttle blade, which restricts flow and introduces the risk of fastener failure.
This upgraded intake air valve (IAV) increases the inlet size to 2 1/4” and completely eliminates the throttle blade, allowing smoother, unrestricted airflow. Removing the blade also removes the possibility of the retaining screws backing out and being ingested by the engine.
A built-in 1/8” NPT port allows for easy connection of a mechanical boost gauge, water/methanol injection, nitrous, or for performing boost leak testing. The back-cut machined lip ensures a secure connection with both factory and aftermarket heat exchanger boots. Installation is quick and can be completed in under 30 minutes.
Features:
-
No throttle blade for improved airflow (race use only)
-
2 1/4” inlet for reduced intake restriction
-
1/8” NPT port for boost, water/meth, nitrous, or leak testing
-
Back-cut machined lip for maximum boot retention
-
Compatible with factory and aftermarket heat exchanger boots
-
Simple bolt-on install in under 30 minutes

About our 5 tunes
Heavy Tow Tune
For those towing from 8,000 lbs up to GVWR (Gross Vehicle Weight Rating). +0 RWHP, +55 ft-lbs torque over factory. A wider torque curve assists heavy loads, keeps a balance of sport driving & functionality, and drops exhaust temps up to 100°F under full load.
Light Tow Tune
For those towing any load up to 8,000 lbs. +30 RWHP, +115 ft-lbs torque over factory. Designed for the weekend tower: boats, small tractors, and more. Unhook and enjoy a sportier drive.
Sport Economy Tune
Fun “unloaded” daily driving around town and on the highway. +50 RWHP, +160 ft-lbs torque over factory. Impress your friends and put a smile on your face.
Hot Street Tune
The bridge between Sport Economy and Race: a little more aggressive, but still behaves nicely on the street. +100 RWHP, +235 ft-lbs torque over factory.
Race / Max Effort Tune
Maxes out the factory turbo. +150 RWHP, +385 ft-lbs torque over factory. At this level we highly recommend a WC Fab turbo mouthpiece, a cold air intake, and a FASS fuel system. TCM tuning is recommended for this level.
Additional details
ATTENTION: No transmission tuning is included unless you select it. If you do, you’ll need to send your stock TCM file to Empire’s engineers to build your TCM tune file. Please be patient. We’ll walk you through the entire process, so no worries, you’ll be in good hands!
EGR Delete Kit
Factory cooler setups recirculate soot and harmful gasses through your engine, causing build-up and clogs that lead to lost performance and proven mechanical issues. Cooler upgrade kits remove those concerns from the equation. Components install with an exact fit for a longer-lasting, better-running truck: less turbo lag for better throttle response, cooler engine temps, less weight, and a cleaner engine bay. Proudly made in Canada.
DPF/DEF Exhaust Systems
The exhaust is a DPF race pipe or a full 4- or 5-inch system (depending on what is selected). It replaces your old exhaust from the down pipe back, removing DPF emissions components, and is built to work in conjunction with the tuning.
