Frequently asked questions
Is EGR delete good for diesel?
Deleting the EGR system can help keep your engine running cleaner. Customization: For diesel truck owners, an EGR delete can be a way to customize your truck and improve its performance. By removing the EGR system, you can customize the performance of your truck to meet your specific needs.
What does EGR delete do on Duramax?
An EGR delete consists of using a delete kit to remove the system. The benefits include an improvement in engine performance, fuel economy and not having to worry about emergency maintenance on the EGR (or even the engine itself).
Disadvantages of EGR Delete
Some diesel vehicles can experience adverse effects like reduced horsepower, increased exhaust gas temperature and engine knocking. In some cases, it can be more beneficial to have an EGR valve replaced, rather than bypassed.
Does EGR improve fuel economy?
The reason is that a engine to run most efficient it needs cold, clean and dry air; the EGR valve lets the hot, dirty, damp exhaust emissions back through the intake manifold with the intention of reducing the combustion temperature. It sacrifices fuel economy for a small reduction in NOx emissions.
