Inlet manifold pressure after map or box

So I've started logging some of the sensor data using an OBD2 adapter and Torque app. I've got my DTUK box on map 2 +0 and it's showing a max boost pressure of 22.5 psi. I've yet to try it in stock mode, but am also trying to log fuel flow, but of course the data might be corrupted by the tuning box since it intercepts the boost and fuel pressure sensors.....
