I had gotten in a boss 550 turbo and i was wondering if anyone knew the wastegate pressure on it. When i first put it on it would boost to about 1 bar and then after a few days it moved down to about half that to about .5 bar or so. Now it is very consistent and it holds that pressure. I just wonder why it fell off to half the original amount. My profec will adjust the boost back up and hold it with stability. I am just curious if anyone else has come across this and what i should do about it.
