100% vane position at idle is usually only during warmup and high idle mode with the engine cold. It's not a tuning issue. My truck has been tuned for 17,000mi and hasn't done it till now. Stock tune still makes noise. I truly believe it's either a leak around the turbo compressor and or exhaust housing, exhaust leak at the turbo and manifold or a exhaust leak between manifold and head. I don't believe it is a wheel to housing contact issue because my turbo had zero play. If it wasn't for warranty and the fact that I may be ordering a '17 I would tear into it and take the turbo off to see what I can find. Mine starts whining at about 6-8lbs of boost and continues to get louder and really whines at 25psi.
