I have a stock style Wastegate now on a 3" downpipe that I have autocrossed with.
Are you guys running an external seeing any benefit ?
 
If the wastegate can manage the flow and keep you from overboosting, leave it.

Where you get a huge gain is adding a blow off valve on the intake side. Throttle-lift causes a compressor stall that can take multiple seconds to recover from, which kills you coming out of corners.
