Excessive power needed for taxi

[Dreadnought1906]

The plane takes off, flies and lands fine.  But taxiing takes a ridiculous level of power - enough to trigger TO configuration alarms.  Not just for breakaway (which can need 1.3 or more EPR on both engines), just maintaining normal taxi speed needs about 1.2 EPR.  A tight turn, where you want power from only one engine, takes nearly full power from that engine.

At first I thought it was simply a ground resistance issue and I would not be able to take off, but takeoff roll seemed fine.  Once I landed and got off the runway the high ground resistance returned.
