YY vs d for pyro


Hi all!
I just winded a 4035 in 5+6 yy 1.32 (incl coating) wire and am stumped by the result, the motor feels stronger than my stock 4525 le from scorpion winded in d. (flown in 2 tdr's
So now my question, the pyro black edition is 1.4mm wire in d , If i wind the pyro in yy what size wire will compare with the 1.4mm in d configuration. I'm looking for similar pefromance but if i can use a thinner wire than 1.4 it would be a bonus as this will only be my second motor so want to stay away from the thicker wires for now.
Thanks appreciate the comments!
