The EBPV closes off part of the exhaust tract to help the motor heat up in colder weather. I would go with the EBPV delete. You'll have a lot more flow and no more goofiness with the EBPV closing while your driving. I'm going the same route when I do my turbo rebuild soon.

(Side note: If your selling your stock turbo and it's in decent condition, I MIGHT be able to take it off your hands. PM me if you like. )
