You mean porting the wastegate? It's a pretty common mod to fight boost creep.

I recomend goin wiht a s5 turbo and manifold. I have a very mildly ported wastegate with a to4 intake side. Boost is stable. Its a better design overall too

Porting the turbo isn't really going to help you all that much. You can port the turbine inlets for a smoother flow but I doubt you will ever notice the difference and unless the turbo is already removed, it's not worth it.

Porting the wastegate is an important mod if you plan on upgrading the exhaust and intake.

If you want to run an upgraded exhaust, porting the wastegate is practically necessary. If you don't, the wastegate won't be able to keep up with the higher boost your turbo is now making. Even if it's a pound or two, that's still a significant increase over what the stock set up can work with.
