Is EGR delete bad for the engine?
Not necessarily. When done correctly with proper tuning, EGR delete can actually help reduce engine stress, lower temperatures, and extend component life, especially in off-road conditions.
Do I need to tune my LBZ Duramax after EGR delete?
Yes. After installing an EGR delete kit, tuning is highly recommended to avoid check engine lights and to optimize performance.
How much horsepower does an EGR delete add?
An EGR delete by itself can provide up to 10–20 HP gain, especially when combined with a high-flow intake elbow, improved exhaust, and tuning.
Does EGR delete cause black smoke?
Not directly. However, if the engine isn't properly tuned after the delete, it may lead to unburned fuel and black smoke. Proper tuning resolves this.
Is EGR delete legal?
No. EGR delete kits are for off-road use only and are not street-legal in most areas due to emissions regulations. Always check local laws before modifying emissions systems.
Does EGR shorten engine life?
In some cases, yes. EGR systems introduce hot exhaust gases back into the intake, which can cause soot buildup and wear over time. Removing it may help extend engine life in performance setups.
Can I install this kit myself?
If you're an experienced DIY mechanic with the right tools, it's possible. However, we recommend professional installation for best results and to ensure tuning compatibility.
What comes with this EGR delete kit?
The kit includes a high-flow intake elbow, block-off plates, hoses, clamps, and mounting hardware – everything needed for a full EGR system removal.
Will this work with other Duramax engines?
No. This kit is designed specifically for the 2006–2007 LBZ 6.6L Duramax and is not compatible with LMM, LLY, or newer engines.
