    Most people are using the R&D multi pressure port adaptor.

    If not that, then you just drill and tap the manifold for 1/8th NPT and screw in a barb fitting.

    Not sure about boost on a stock motor, probably around 6 psi. I saw 7.5 for breif periods (before the boost limiter kicked in) with the FF exhaust, RIVA intake, and manifold upgrade installed.

    The easiest way without tapping the manifold is to use the R&D adaptor. With only the power filter & manifold sleeve installed I was seeing between 7.5-8.0 depending on weather. However, without the powershot or aftermarket ECU to eleiminate the boost limiter that is only sustainable for several seconds before the TB closes & drops it to 7.0-7.1.
