dualport vs single wastegate

[T-Type85David]

I was wondering the pros and cons of this swap?? i believe there is a diagram of how to hook up a single rather then the dual wategate. Why is this? My dual is fine with me but if a single helps out alot then i would love to know why? Thanks

I believe if i remember correctly... The dual port was not adjustable and the upgrade was for the ability to turn up boost with the single one. I might be wrong its been a long time.
