Its compressor stall, or bark, not surge. Pretty typical with the shift\lock algorithm in the newer trucks. One of the dangers running a lot of fuel thru too small non-optimized turbine housing.
When the rpm's drop on the OD shift\lock the ECU defuels and the exhaust flow won't support the boost level.
A good turbo correctly sized should take care of a lot of that problem. If it doesn't, run it up to speed in drive then get out the throttle before shifting to OD.
