uncontrolable 14b boost?!?

Ported o2 housing hopefully will take care of it.

1. Port the turbine inlet and remove as much material on top of the waste entrance to create a direct path to it. IMO this is the most important part when it comes to porting for creep.

2. Port the area behind the flapper lever to allow the flapper to open until it's parallel to flow.

3. Port match both the o2 hosing and gasket to the turbine side.

4. Remove the divider where the wastegate path merges back to exhaust.

Many including myself have done this successfully, happy porting.
