He means to use an extra analog input on the PROcede to hook up to a boost sensor like what my gauge has so that you can measure the REAL boost which the engine is seeing, after the throttle plate (manifold pressure/vacuum).
As we all know reading intercooler pipe pressure can be confusing if people don't understand why its not the same as intake manifold pressure. Its nice to have a boost reading that you know its actually what the engine is seeing.
A prime example is when the ECU uses throttle closure to control boost spikes, my boost reading will show boosts dip or stay solid while the throttle closes, but the PROcede reader shows boost spike in the intercooler pipe (because the wastegates remain closed building boost, but the throttle slams the door on the airflow, causing it to build up in the intercooler pipe)
