You're flying at V2 with 30° bank!
That explains the 600. wow, this is certainly an e-ticket ride!
Not sure of the specifics, but I would look at getting the bank angle down, if the same track works with EO works at 15 degree bank angle, why the 30 AE?
It also may help to look at starting the turn at the min of 400, with less bank angle...even 15 EO is a stretch, and a lower turn start would give you some extra room, but there may be other reasons not readily apparent.
