If you have boost creep simply smooth the leading edge from the uppipe into the WG port and you'll be cured.

Interesting...are there specific UP's that are more likely to cure the boost creep issue before it starts? It just seems like if the WG is too small to let enough exhaust pressure out, you're going to get creep...no matter what.
