Default MBC with or without TCV?

volvo 850 t5 96 m4.3 , i installed a MBC to try to give a little more reaction on the low-mid rpm. its working, more steady boost load and its not overly boosting , based on my stock gauge its around 1-2 psi when its start kicking (i guess).

MBC is between the wastegate and the tcv. ive seen some people saying to run it like this . other say to directly bypass the tcv , thoughts?
