Once the hose is routed through the firewall, where have all of you connected your hose to? Somewhere on the intake manifold? T'ed into a vaccum line? Any pics would be great OR just hookup spot would greatly help. IUP99Snake...'bout u?
T into a vacuum line. That's what I did. On my model, there is a vacuum line that goes into the upper intake plenum on the underside of it directly behind the throttle body. I followed that line up and T'd into it.
yea... i second that. Try and find a place to T into as close to the manifold as possible, because some vacum lines have check valves in them. You wont read any boost if you find one of those.
