7.3L Power Stroke EBPV Delete Guide And Procedures

A 7.3L Power Stroke engine can be made more efficient and perform better by taking out the exhaust backpressure valve. Reducing pumping losses both in and out of the engine can improve efficiency and performance.

Despite the valve’s relatively small surface area when it is in the open position, numerous accounts suggest that its deletion will result in lower EGTs and better turbocharger performance on the whole.


In effect, the exhaust backpressure valve works by restricting exhaust flow in order to simulate a load on the engine and reduce the time it takes the engine to reach operational temperature.

In order to connect the turbine outlet of the turbocharger to the valve, it is mounted as a butterfly type. With the 7.3 Powerstroke EBPV Delete, a simple linkage is used to connect the EBPV. An actuator controls the position of the EBPV using a plunger/piston that moves forward and backward. Control of the range of motion is controlled by an EBPV regulator/solenoid which allows motor oil to flow into the actuator.

When the HPOP reservoir is heated, the EBP sensor positioned at the front of the reservoir determines the correct position of the EBPV. The EBP valve is held in the open position once the engine reaches operating temperature and the EBP system is disabled.


Since diesel engine combustion efficiency peaks only when it has reached operating temperature, it could be argued that this system was designed to reduce emissions.

Reducing warm-up times means less fuel dilution, as a cold engine running at idle is one of the most common ways that fuel is diluted. No matter how it is described, the restriction causes the exhaust stream to be obstructed when leaving the turbine housing, and thus results in a loss of performance and efficiency.

In case the EBPV is deleted or disabled, there will be two negatives: 1) the engine will have to wait longer to reach operating temperature. Typically this would not pose a significant problem in warm climates, but it could have negative implications for engines that are started in extremely cold environments, where fuel dilution is already an issue.

1) the EBPV will cause the engine to produce more emissions in comparison to the difference in the amount of time it takes for the engine to reach operating temperature without it. Fortunately, most people won’t be affected by this, but as an emissions control device, the EBPV has to be fully functional during emission tests in parts of the world where these tests are conducted.


In addition, removing the valve, gutting it, and disconnecting the EBP regulator is also an inexpensive alternative. Replacing the butterfly valve requires replacing the freeze plug or a similar piece of common hardware and then replacing the butterfly valve.

In the retracted position, the piston remains engaged on the actuator when the regulator is disconnected. One problem with this method is that it will throw a soft DTC and two, it can lead to an oil leak within a reasonable amount of time. It is useless to simply unplug the EBPV in order to inhibit its operation when eliminating the restriction would provide the obvious benefits.
