EBV Delete Basics

EBV Delete for 7.3L Power Stroke Diesel

The exhaust backpressure valve is a device on the 7.3L Power Stroke that helps the engine reach operating temperature quicker. While the EBV does its job, the problem is that the valve presents an exhaust restriction, even in the open position. And when the valve is closed, fuel economy and performance are greatly diminished until the truck is completely warmed up. If you live in a region with relatively warm weather, you may want to consider ditching the EBV for better performance and fuel economy. If you are handy around the shop and want to save a few bucks, you could always gut the EBV yourself. A noteworthy option for 1999.5 - 2003 model year engines is to purchase a non-EBV turbine outlet direct from Garrett, the OE turbo manufacturer.

How The EBV Works

The exhaust backpressure valve (EBV or EBPV) on 7.3L Power Stroke diesels is a butterfly valve located on the turbocharger turbine outlet. The valve closes when the engine is cold thereby increasing exhaust backpressure and essentially simulating a load on the engine in order to bring it up to normal operating temperature more rapidly. When the engine reaches normal operating temperature, the valve opens. Even when the valve is in the open position, it is an exhaust restriction. Deleting the EBV allows for a more free flowing exhaust, which can increase turbo performance and reduce lag.


EBV Delete Pros & Cons



Reduced turbo lag

Engine may require more time to warm up, especially in extremely cold weather


Reduced exhaust restriction


EBV deletes are available for all 7.3L Power Stroke diesels. If you live in a climate that has cold winters, you may consider leaving the EBV in tact since it is a functional component. If you don't want to spend the money to delete the EBV, the butterfly valve can be removed and freeze plugs can be used to seal the holes. For 1999.5 to 2003 model year engines, one of the best solutions is to purchase a non-EBV turbine outlet direct from Garrett as opposed to an aftermarket unit.
