What about Iowa, it is so hit and miss around here that you can never predict the weather. All I would have to do if I wanted to use the EBPV is just plug it in correct? I have a 97 so it doesn't have the high idle warm up option on it. Just wondering.

Yes the noise does go away once it warms up so I guess I probably could live with it. The thing is, there really is no point to unhook it in the spring since it probably wont be cold enough for the computer to kick it on. I think I will try it here before it gets too cold just to see if it makes a difference and go from there, unless someone else has some more feedback. Now, we wait in suspense!

I think I posted above as -20 being the point where I turn mine on. Today it is -11 and I will probably leave the switch for the EBPV off. For you guys in climates where it does not reach -20 I would not worry about unplugging it.
If you leave it plugged in and it seems to be cycling more than you want it to and you live in a warmer climate it is probably malfunctioning anyway. Mine never cycles in the summer. The most common problem is that the line from the right exhaust manifold to a back-pressure sensor that is mounted on the HPOP reservoir becomes clogged with soot. When this happens the EBPV seems to get a mind of its own. The line can be removed and cleaned out with a piece of wire chucked up in a drill but it is easier to just replace the line. Like I said though if you live in a warmer climate just unplug the EBPV and forget it.

By the way I should have added that if you want to leave your truck idling for more than a couple of minutes you should install a idle controller. Ford makes one or you can build your own with a potentiometer. The 99-up trucks idle up on there own but the 97-older ones don't. If you let the PSD idle for an extended period of time it will cause what is called wet stacking and it is hard on the engine.

The rest of my opinion on the subject is that a big ol' flapper valve in the middle of the turbine outlet is just about the dumbest thing I've ever seen installed on an engine. That's why I gutted mine years ago. I think that if it were crucial to the longevity of the engine then every diesel would have one, but they do not. I'll take the performance potential of having a free flowing exhaust over the creature comfort of the cabin air warming up five minutes sooner any day.
That's my whole two cents.

Yes when truck is off it is open. It takes oil pressure to close it.
Cookie88, The reason Ford installed the big ol' flapper valve in the middle of the exhaust is because of the flack they were getting about the heater taking a week to warm the cab in the older pre-psd diesels. Many people want creature comforts and when they leave the dealer for a test drive freezing there gonads off and still being chilly when they return to the lot from there test drive they tend to look at another brand that will give them a little warmth.
