Alright, I know what and how I install my hallman mbc controller. I can cap off the nipple on my intake that the stock bcs was lined to and get rid of the vacuum hose that was connected to it. But as for the stock bcs are you guys just leaving the stock bcs in and out nipples completely open with no vacuum hose connected? I'm concerned about moisture getting in and ruining my stock bcs and throwing a engine code down the road since I'm still leaving it plugged in since I have a 2g. I've heard of people looping the stock bcs, and my searches bring up endless how to hook up a mbc LOL.

I'm hoping me installing this mbc will help stabilize some of the boost creep I'm getting (if it is boost creep) I can floor it and I can push 20psi + probably with the stock bcs plugged and vacuum lined in with my 16g and all supporting mods installed although I'm still on stock ejectors and pump with no tune LOL.
 
If you're worried about it you can cap off the nipples of the stock BCS or loop the two. It's not going to be moving any air other than what the solenoid displaces when it opens and closes.

You are just keeping it so that the ECU doesn't fault due to a missing load on it's output.
