Default Car running lean at full boost

whenever i hit full boost (which is about 6psi for now) my a/f gauge goes to lean and i feel my car kinda hold back power. some people have told me that it is the missing link that i have installed since the vafc needs the signals from the MAP and the ML is blocking those signals. would this be the problem?

If your doing the hack then YEAH! It needs to reap the map signals.
