Most any good performance shop can port the wastegate if you give them instructions:

It's virtually pointless to "port and polish" anything other the porting the actual engine, though if you are very bored you can gasket-match the intake manifold ports.

The S-AFC is a piggyback fuel controller and will allow you to tune the fuel curve.
