conflicting WB and blm readings

7165 ecm, 383, 6e

starting to tune my maf tables to get the blms in line (idle 108 and cruise 108). I started to lower the grams/sec in the first and second tables. the blms got closer to 128 but my WB is reading lean at idle and cruise (16-17). It seams that the closer I get to 128 the engine is running hotter and leaning out to much.
Any suggestions?

Replace your NBO2 sensor, since it is probably fouled from the excessively rich condition you've had.
