Boost stays at 10 psi.

Hi. I have a very cheap MBC off Ebay. But it seems to work.. Kinda. I dont really know. All the way turned down the boost stays at 10 PSI. is that normal? I turned it down because it was hitting 16 psi. and I have stock pump and injectors. and it seemed almost like there was no in between. But it seemed like it hit 16 then sit at about 14... Just wondering if this would still be considered as boost creep or what?

hitting 16 then settling at 14 is a boost spike. Staying at 10psi when it's all the way down is normal. You can't turn the boost down any further than stock (what the wastegate spring is set at ) which is ~10psi.

K thats what I wanted to know.. Thanks!! Its just I was told that stock was 7.. thats why I was asking. But boost spike is caused by my MBC correct?
