I understand that having a higher tps setting gets you into PE faster....and it is merely a means of fooling the ECM.
With that said, is setting your tps at a higher voltage beneficial with a ported plenum?

It may get you into PE mode a millisecond faster, but I don't see any benefits at all. Just set the TPS to spec, verify you get a full range of voltage from 0-WOT...that's about it.
