The EBPV is the exhaust back pressure valve. In cold temperatures like 30-40 and under, this valve activates. It's a butterfly valve that partially restricts your exhaust, raising the exhaust pressure and making your engine work a little harder. The idea is to make your engine warm up quicker and it sure does work. That's obviously the pro to it. The con, or what some people see as a con, is that it makes a lot of noise and somewhat lugs your engine down. The valve shuts off once the engine is warm or if you step on the gas enough. Hopefully that answered some questions. There are some threads around (search) that talk about disabling it and whatnot.

There is a plug under the compressor of the turbo that you can unplug to disable it. We saw a run of single digit temps here lately and it was making a howling noise so i unplugged it and no more noise. I'm going to get a chip with a high idle to make up for it.

Another con... if the sensor goes bad, the butterfly will close on you going down the road...70 to 40 in a hurry. Can cause a dangerous situation! Unplug it, if you dont like it, plug it back up. Mine was unplugged for 2 years, and I finally had to remove the turbo, and gutted the pedistol, and removed the butterfly from the housing while it was off the truck
