Help needed - manual Boost control issue
 

Hello, I’ve got my 1997 850 t5 and I was going to install MBC, however, when I was bypassing the BCV by putting my green hose from my turbo to my MBC towards my wastegate I somehow managed to only make HALF(0,5 BAR) the boost I did before(1BAR) with the BCV. I can’t find any posits where people experience the same. So I was hoping that a Volvo expert could explain where it went wrong
