well i'm sure everyone will agree with me that you
have a 99.9% chance of needing a new bypass valve to
fix that stalling problem.. as far as the boost
problem it could be something as simple as a cracked
hose.. what you might want to do is build urself a lil
contraption.. a PVC pipe that fits the hose that
connecto the the MAF (right before the air filter) cap
this pvc pipe and put in a valve stem,, like from a
tire or whatever.. get urself an air compressor or
figure out a way to give urself about 15psi continuous
air pressure.. listen for leaks.. wherever you hear
it.. replace that hose.. lil tip those small lil hoses
that go from ur manifold to ur bypass valve and the
other two that come off of there most likely need to
be replaced.. i jus did mine with some steel braided
lines i special ordered from autozone (2$/ft).. not
only do they look pretty but they're damn durable :)
