Advice on tuning A/F after dyno session.
Hey everyone how are ya? 
I went to the dyno this past saturday for the first time after putting the superram/219 package together on my corvette. The car is running rich down low with the 22# injectors, and slightly lean up top. Looking at the following graphs, what would YOU personally be looking to modify in the BIN after seeing these values?
I assume... WOT %Change to Fuel/Air Ratio vs. RPM
...but any other tips?
This is the '165 ECM & $32b
p.s.
We have a lambdaboy unit to test with while not on a dyno.

Depending on how fast he opened the throttle alot of that down low richness might be AE.
If you not out of duty cycle / injector, the PE vs RPM will work, but it's often best to deal in some PE vs TPS.
By using the PE via TPS you can get a smoother transistion in AFR at all operating ranges.
