Do you mind sharing what powdercoating "home kit" you used? Assuming that because it was done in your backyard - which is great i might add!

no i havent. would that actually make a difference over a 3 port? i know you can run a lower psi spring and run higher boost pressire

Yea, those are correct. It also allows the turbo to spool quicker because it actually keeps your gate shut. I know you have creep, and I've read in a few places that 4-port ebc's helped/fixed it (depending on severity of creep, of course).
