There are a couple of simple ways to trend your a/f data. the easiest would be to run any scan tool and look at your LTFT on both banks. This will give you a general idea of how rich or lean your enigine is running. Secondly, but, not as easy is to use the Palmer Engineering OBD software and build two tables and look at both LTFTs and STFTs. This method would pinpoint those load/rpm points that are not in range. In your case it would find the rich areas of the load/rpm map.
I recently did something similar, then, used the SCT tuning software to modify the load/rpm map points. My issue was the inability of the VEC to accurately accomplish that 3D mapping. In my case the mileage went up substantially.
