I still think you're running LEAN btw... Typical best torque numbers are going to made at WOT with a number somewhere in the mid 12's on the A/F. Even in a modern EFI motor the WOT numbers are going to be far fatter than what your dyno run is showing.
I was at the dyno all day yesterday with a EFI 598 ci whipple supercharged motor - and when the A/F got anywhere near 14's the run got aborted. Now, we'll all argue about the fact that this is a supercharged motor and they like "fat", but my point is that 14's on a performance motor at WOT is quite possibly close to hurting something.
