In your case, at 12.5 psi, the corrected parameter will read up to 24.5 psig. If you need more than that, then DL and install the latest romraider defs and log "Manifold Absolute Pressure (Direct)" which has NO effective limit.
Thanks tea cups, I went out tonight and just logged all the relative pressure parameters and worked out what was going on, thanks fo rthe advice though - appreciated.
