Big ports are nice on a turbo engine.

I'd definitely port the intake.
TII exhaust ports are already pretty big. It's up to you whether to port them or not. If you want to keep it mild, I'd extend the closing and increase the width by around 2mm (basically, go out to the edge of the stock bevel, then make a new one). Then give the opening edge a slight curve and smooth everything out. I've done that before on NA engines with good results, and I imagine the gains would be even higher for a turbo motor.
