Just installed the C337 V2.1 from Carenado into P3DV4.  Install worked fine.  However, in level flight with controls centered the plane goes into a slight left bank.  To get the plane to fly a straight heading one has to put the plane into a slight right bank.  Considering this plane is a pull-push engine configuration there should not be much if any P-factor effect.  Any others experienced this effect?

1. A left banking tendency should be corrected with right rudder (trim), not opposite aileron.

2. Confirm fuel load is symmetrical ?

3. Haven't noticed any FDE differences with any plane in v4 so far.

Weight and balance...as J35OE mentioned, make sure you don't have a fuel imbalance. Also, if set up with 1 pilot, it may roll to the left a little.
