since the cold weather is here whenever i start my truck up i hear a loud blowing noise coming from the motor that almost bogs down from my high idle and kills the truck... it used to happen when it was warmer but for only a second until i tapped the gas petal... i have a ts chip and 4in turbo back exhaust.... any help
thanks, dylan

Yeah, the EBPV is designed to help warm the engine in cold weather. It is essentiall an exhaust brake. Best thing is to just unplug it, and never worry about it again. (since driving against an exhaust brake isn't real good for fuel economy, and if it gets really cold, some people have to wait over 30 min. before it'll open up) The plug for it is underneath the compressor (intake) side of turbo. Simple two wire plug. Just unplug it. It won't throw a code, so no worries.

no issues wiring that up to a switch, is there?

To my knowledge, no. I haven't done it, as I don't need an exhaust brake. I believe Bully Dog makes a "kit" for it, though they want big $$$$ for it. I guess they're pretty fond of their work I suppose.

my thought is you could break one of those wires and just throw a toggle switch in. that way you could control whether or not the EBPV engages DURING WARM UP ONLY.
if you wanted more of an "exhaust brake" you would have to find out what voltage (prob 5V?, perhaps 12V?) is operating the EBPV and run that voltage through your switch directly EBPV plug.
i believe somewhere along the line i have heard that using the EBPV as an exhaust brake can be harmful to PSD's. can anybody confirm or deny this?

Yes many people have done this. I'm actually going to do it eventually

I haven't heard one way or another. I'm not entirely sure where a standard exhaust brake would be installed though. Probably in the same place as the EBPV. I've heard of a few people using the EBPV as an exhaust brake though. Not so much for daily applications, but if you tow a lot, then it'll surely help save your brakes.

Maybe someone who knows a bit more will jump on and fill us in.

There's not really much on it other than how to do it and how well it works. You can look in the mod section of the 7.3s for a lot more on it. But no, you just run the two wires to a switch, and there ya go, control over the EBPV. Some speculate that since it was designed to hold back pressures at idle or high idle to help warm up, then it wasn't designed to hold back pressures at 2000+ RPM. It makes sense but quite a few people have run it with no problems. And heck, if it DOES decide to break, then it'll either quit working or the parts will just go down your exhaust pipe and rattle :hehe:
