His boost pid hes using the Maths, Airflow, boost which is correct.

I have found on the LT4 you have to log the PID, Manifold Absolute Pressure - Hi Res in addition to Intake Manifold Absolute Pressure for proper MAP readings. To be honest I had to do this so long ago when Gen V stuff was new that I forgot exactly why. But I do remember having the exact same issues with the LT4 where the boost reference and MAP reading was incorrect. Do you have another suggested fix for the incorrect value?

We solved this on HPTuners forum long ago....could the ZL1 have the same nuance? It just might be possible.....
