OK. I finally got my new turbo on and it spools nice and fast! The only problem is that I cant get this damn MBC to work! It either lets me hit 10PSI (which sucks), or 20+ PSI (which sucks worse). There is no inbetwen. I back the set screw all the way out to where there is 0 pressure on the stopball ( I can hear the spring and ball rattle) and I hit 10PSI, or if I turn it a 14 of a turn in to where the spring is barely putting any pressure on the stopball and I get ungoldly amounts of boost. I cant figure it out! I literally spent all day searching the internet, trying several different springs stopball combos, and whatnot. I cant figure it out!! WTF? Please help.

Is this a home made controler or what? Sounds like the spring might be too stiff.

I'll sell you mine (MBC) never installed still in bag for $20 if it helps. Went electronic.

If you are selling the car you always remove the MBC altogether and return to stock.

Those are my two ideas for the 'easy' fix.

Get a hold of Kris. He's a stand up guy. I'm sure he'll fix yours or hook you up with a different one. I'll PM you his number.

Marcus, check you PM's please.
