I thought I would do a little write-up for people to look at regarding a loss of power/funny noises coming out of the exhaust.

The 7.3L came equipped with an Exhaust Back Pressure Valve (EBPV). The EBPV was equipped to provide quicker warm up times, and to keep the engine warm in colder climates.

The way it works is fairly simple. The PCM opens and closes the EBPV following certain preset parameters. Many times, the operation of the EBPV is normal, but the loss of power can be an annoyance. Many people have unplugged or gutted the EBPV, and have no complaints whatsoever. A simple way to test your EBPV is to simply unplug it. If the operation of the EBPV is causing your power loss, when you unplug it, it won't close, and your exhaust will flow freely.

Just thought this might help people during the colder times of the year. :usflag


ON EDIT: Here is a pic of where the plug is. On the late-99 & up super duty, its fairly easy to reach in from the passenger side and unplug it. Just flip up the metal clip, and unplug.

If I may add on you may also unplug the plug on the ebp sensor and this will disable the ebpv. It is easier to get to disconnect, or recconnect for that matter. Located on the top front paassenger side of the engine.

yeah, I unplugged mine from the sensor and the other day, the valve was closed cause my truck sounded like a jet! It does sound awesome, however very annoying when the valve is closing when you are driving and you have no power until it is warmed up. I will be unplugging mine at the actual pedestal base.
