Oh well abilify is unique it's a partial agonist so it weakly activates D2 where every other AP inactivates it. I can't guess what the effect on BP is because abilify acts uniquely depending on the endogenous dopamine levels in any region it can be either activating where there is low dopamine or inactivating where dopamine is high because it blocks the receptor but only signals weakly...

Yeah if you find out what it was let me know...
