EBPS and EBPV?
Are the EBPV and EBPS part of the same system? I assume the EBPS supposed to read pressure and open or close the EBPV? If this is the case is it safe to assume that since my EBPV opens and makes the jet sound in cold weather that the EBPS tube is not clogged? Sorry if I'm totally off base here.

The EBPS is the sensor that detects the pressure in the manifold, and it is part of the system. The PCM uses that to determine how much pressure is there when the EBPV closes and how far it's closed. I notice that when it's not real cold mine closes a little, then when it gets in the 20s, it seems like it closes off more along with the truck idling up. However, the EBPS is also used by the PCM for fueling to some extent -- there have been several discussions about it. I plan on gutting the EBPV, but I'll keep there EPBS. There are fixed sensor replacements out there, and that's usually what starts the discussion about how much it affect fueling. I know that several have gained 2-3 mpg after cleaning a stopped up tube & sensor.

I unplugged the EPVP and the EBPS. To tell you the truth power and mileage has been more consistent than ever and it's been that way for about a year. All year city driving I can count on a minimum of 13 mpg. Before I unplugged everyting on cold days I had the "jet" noise and lousy mileage in winter weather ...10-12 mpg. I know some people will disagree but unplugging both devices really helped me out.

No I think he meant unplug the sensor. You can disable many sensors on a 7.3 just by unplugging them and the truck runs "just fine" without it. You may notice a change in the way the truck idles. Some people say it's better unplugged. Your mileage may vary (literally).
Saying that unplugging them will result in increased MPG is basically confirmation bias. In reality, you probably won't notice a difference in normal operation.
