Frequently asked questions
Is EGR delete bad for the engine?
With an EGR delete, you can reduce the amount of carbon buildup and extend the life of your engine. This can also help save you money on repairs and maintenance costs over time. Cleaner Engine: While the EGR system is designed to reduce emissions, it can contribute to engine deposits and increase pollution over time.
What are the benefits of blanking the EGR system?
Lowered Engine Temps. Improved Throttle Response. Improved Economy. Reduces Oil Contamination. Reduces Carbon Deposits in the engine.
Does EGR delete increase smoke?
Black smoke is caused by too much fuel going into the engine resulting in incomplete combustion meaning you are blowing unburned gas out of the pipe ( burning oil makes white smoke). Removing the EGR will not cause black smoke but it won't improve the situation either.
Will EGR delete cause black smoke?
You get black smoke from incomplete combustion because the excess fuel in the engine causes the black smoke. Deleting the EGR system does not cause incomplete combustion. Therefore, it will not change the color of the exhaust.
