I seriously doubt the motor is ported.

I have a ported s5 engine with a s5 turbo in my TII. I running the rb 3" trubo back exhaust. I was getting a solid 10 psi with a ported wastegate. I later took out the turbo and ported the turbine inlet to even out the runners and smooth them out. I ported the inlet to the wastegate, i mean i ported the **** out of it and i polished the crap out of the curves from the turbo into the wastegate. You have to be careful when you redirect the flow into the wastegate since some areas dont have much material behind it. After this i hit 8psi, the boost is a little bit more responsive. The car seems to pull just as hard as it did at 10psi.

I've never had any problems with my TIIs except for the time i ran a 3" single exhaust then i was hitting way too much boost creep.
