Frequently asked questions
Should I delete my EGR cooler?
Installing an EGR delete kit reduces costs on repairs and fuel costs, as well as decreases soot deposits that an EGR valve produces. Disabling it prevents harmful contaminants from being reintroduced back into the engine, resulting in problems. When the engine's performance increases, so does the fuel economy.
What is the benefit of EGR delete 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)
Technically you can drive without a working EGR valve.
The role of your EGR valve is to reduce the number of toxic NOx gases in the air, so if it isn't working quite right, more toxic gases will be released into the air. For this reason, we don't recommend driving without a working EGR valve for too long.
Does EGR delete increase horsepower?
Deleting the EGR system reduces carbon buildup and improves airflow to the engine. This will result in better performance and you may experience improved throttle response, increased horsepower, and greater fuel efficiency.
