This is what we were seeing on the computer side, the orange/tanish line is MAP kPA. It's near atmosphereic at the start, and slowly tapers to ~85 kPa (97 kPa was nominal) @ 7500 RPM.

Edit: This was done with no filter, different pressure tap location. Torque fell off the face of the earth @ 6500 RPM and the car only laid down 550whp - Mustang. The setup was literally a SB2.2 auction motor. The cam was roughly 268/274, .750 lift @ 0.050, 13.6:1 compression, on 109 Octane.
