As for Power Balance of Ford, the Part No. of this vehicle (F-150, 2014) engine is EL3A-14C204-ASA, which is a new Part No. and we haven't included this part No. in our database in our current and previous versions (V5.00, V5.10 and V5.11), so our Ford softawre can't support the Power Balance for this vehicle (F-150, 2014), accurate to say it can't support this new Part No.
As you said it can work in V5.1, I think it is the same vehicle mode, but different engine Part No.
