yup, remove the check valves, install a straight section of hose from the manifold to the map sensor.

just go out and look at your car, jeff, the map sensor is attached to the firewall, on the passanger side.
the stock GT map sensor has a blue sticker on it IIRC. wink.gif

why are you adding fuel @ lo-throttle points?
you SHOULD be lean under lo-throttle, off boost conditions.
as your approaching boost, and into boost, you should be 11.5:1
everywhere off boost you wanna be between 14-15:1

if your "wideband" dont give you an exact A/F ratio #, then its NOT a wideband.
those "lightshow" regular o2 sensors are pretty much usless for tuning.
