Looking at the AFR I'd say it's an AE MAP issue!

See where you go WOT and AFR drops to where it should be? That is the AE TPS working. Then the AFR goes up real lean and you've got a couple seconds to recover and AFR comes back down to where it should be. This is AE MAP not working!

AE TPS is a fast pump shot while blades open.
AE MAP is the longer pump shot to finish the transition.
