EBPV closing when HOT

My chief has the exact same truck as me except its auto and has about 190,000 on it. this morning at shift change he showed me....

his truck was at operating temp (R in normal), and idled fine, but when the engine reved to about 1200-1300RPM the EBPV kicked closed, RPMs dropped about 300 or so, and the valve seemed to stay closed at ANY RPM above 1200-1300. was only about 45 degrees this morning.

ya, I unplugged mine....
Facing your truck with the hood open, it's under and to the right (driver's) side of the turbo. It's a two-wire plug. Unplug it and you're done.....easy as pie

I have heard that you will see longer/shorter warm-up times depending on the outside temp (I live in tx so I didnt see any change).
I have also heard of folks loosing some mpgs (around 1.5) after doing it, but once again I didnt see any change.

I found this info in a ford manual:
Exhaust Back Pressure Regulator
Exhaust back pressure is controlled to provide more heat to the coolant for cab heating when ambient air temperature is below 5C (40 F) and engine oil temperature is between -10 C (15F) and 83C (182F) during low load. At high load, high speed conditions, the back pressure system is disabled.

So do you loose MPG with unplugging it? I would think the motor could breathe better giving you better mpg's?...

You actually gain MPG by unplugging it. I did it on my 7.3 and it only took about another 30 seconds to warm up
