P0087 is low fuel rail pressure. you likely drained it on one of your higher tunes. do you have the fprv shimmed or a race plug installed? if yes, then its time for a lift pump. if you have both then you may need a cp3.(this one is doubtful, I'm sure you'll answer no to one of the earlier questions before getting this far)

P0401 is insufficient flow to the egr. I'd just block and fingerstick it if i were you/ and or delete the sucker. should fix your issue and be better for the engine.
