Hi Jim, Thanks for responding.

I do have a stock MC-1 intake manifold and it has a
little 2" piece of rubber hose between the head and
intake manifold. That should be OK right ?

There is another  connection right next to the TB that
I wasn't sure about (What is this for ?). So I just
routed it to intake vacuum.

A third connection coming off the hot side of the
turbo just before the intercooler inlet was also
routed to vacuum (could this be a problem ?).

I do have a bypass valve (brand new) in blow off mode
attached to a intercooler outlet (intercooler from a
KH turbo) but I don't think its leaking.

Wouldn't a leak send me to the lean side anyway ?
