when was the last oil change?
about 60 miles before the trip this weekend, approx 400 since change. I have not physically tried to move the valve by hand yet. Kinda working on it between jobs at the shop.

I've heard of EGT's doing things contradictory to what i would think so I'm no help there. Any chance there's something wrong with the turbine side and its simply not spinning the compressor fast enough?
Exhuast tone doesn't sound out of place or restricted like it does when the valve is def fully closed.
Only mod is downpipe and straight 4" pipe from downpipe. Truck has never had a tuner or programmer on it.
