If I put a manual boost controller I can eliminate the majority of th e vacum lines. My question is, I am running an autothority maf and chips, and my boost drops from 15 to about ten in the upper rpm range. If I put a boost contoler on will this set up work with this setup?

Just running an MBC is not really going to delete a lot of the vacuum lines under the intake, you would need to do a venturi delete and hose update to get rid of the lines. What year 951? Also, the boost drop is probably due to a worn out wastegate. I would put on a Tial along with the MBC.
