    I hear that. I would put bigger valves and a RV cam in and they would zip.

    Shave 0.024 off the head, chamfer & polish all valve flanges in combustion chamber, get some high domed pistons/ cut the skirts equally to balance, copper head gasket (your gonna need it)

    End result should be right around 12.5:1 compression that in no way will you be able to run pump gas thru it ...:D

    Yeah didn’t the 2016 have issues with tranny fluid being low as well as leaky diff issues, if I recall correctly..?

    OP, I’ll be really interested to hear what this turns out to be. That sounds like my ‘16 when left to idle for awhile when the injector cleaning cycle kicks in for about 15 secs. except it’s at 6 of the injectors. When in bypass mode they are noisy. Put a long screwdriver on the valve cover there and hold the handle to your ear. See if it sounds like it’s in the cam/valve train. Compare the sound along the cover and with the other side. Odd it goes away when reved.

    There’s a low pressure pump in the tank that only pushes fuel to the high pressure pump on top of the motor at the injector rail.

    To take it a step further why 2 pumps ? If all the second pump does is maintain pressure at fuel rail , a one way check valve just about anywhere behind the rail with 1 good pump (like in past) is fine, no need to reinvent the wheel...
