Does the EBPV affect EGT?
Yet another EBPV question...
Recently installed my Walker BTM so I've been watching my EGTs since. First time I drove it, was about 65deg out in the afternoon. Went for a test drive after the install. Noticed that temps were lower from what I remembered, and didn't rise as fast (esp WOT).
Next time I drove it, it was ~40deg out and 10pm - truck had been sitting outside all day instead of in the "warm" garage. Temps seemed higher, but then started to behave after halfway home (30min drive, mostly interstate). Temps didn't seem to be an issue that morning (truck had been in the garage then).
Am I imagining things? All I could think was that the EPBV was restricting flow, but ??. I might have to do some cleaning per that previous post...

well, the EBPV is either open or closed, yes it can create a major increase in EGT, since it's restricting almost ALL of the flow out of the turbocharger. with the BTM on, you could clearly hear the hissing noise under the truck, even with all windows up. it's loud once you open the exhaust system up.

When i had my truck straight piped and still had an EBPV, i could stand directly behind the truck when it kicked on raised idle (factory, not my chip), and when the EBPV closed, i honestly couldn't hear the engine over the roar of the EBPV at around 900-1000 rpm.
i deleted the EBPV from my truck, i haven't heard it since then
