IIRC the standard/factory settings on that ESC add timing and boost in (DRRS or DDRS i think it's called.) Think mine defaults to setting 5.
But it possibly depends what firmware you have on the ESC.
Also, the endbell of the motor has a slot at the bottom. If you loosen the 3 screws on the front (slightly) you can adjust physical timing to 0 in the slot. (then retighten the screws)
Think stock might be 5 degrees.
