So just got MY2018 back from the dealer. 10k miles replaced cam phasers, camshaft, and cylinder heads with all corresponding components. Truck also had and has S&B intake, magnaflow black exhaust and turbo smart blow off valve. Everything drives and feels back to normal except the blow off valve is extremely quiet and sounds like hardly anything blowing off for lack of a better way to describe. How do I get the loud blow off back?

Day 2 driving it and getting on it some more looks like the sound is creeping back up. Dunno but maybe the system coming back from reset.

I have the same problem. I think / hope it's a wiring harness issue so check your connections. I am yet to get under the skid plate and sort it out.
