this is the screw to adjust the boost. the seal on this is not cracked or broken either.

These are the o-rings on the top of the MBC (obvious) anyways, these are loose, and I can hear air coming out when im just sitting there with the screw turned out a few turns. Is that the problem?

Basically any setting I have it at, it will go to whatever it wants.

I hear of people often that say their turbo xs mbc's have problems..mainly spike problems I think..If there is a real issue with it then you can always sell it and buy a cheaper one like a Joe P...Not many people complain about those
 
what exactly do you mean by "loose"? They look just fine in the pictures
 
That's just the way they are, the one I had did the same things you describe. Except mine actually sort-of controlled boost.
 
get a joe p, got one a week ago set it to 15, doesnt spike or any thing stays @ whatever i have it set @ :thumb: boostcontrollers.com has them 45 shipped...
