The reason of Boost creep the location of wastegate , last owner install in such funky location with knight sport hight flow , there is no way 38mm wastwgate will be enought !!
But beside that , every thing work fine, lets why decide still keep same location , but just upgrade the wastegate instead

High velocity spot with bad entry angle means you need a lot of wastegate surface area.

That's right, but still cheaper to build manifold
