around 14s should be fine, don't look too bad as is. What did you tune with?

 

apexi vafc....but the fuel was untouched in this chart just the vtec was lowered

 

14s is way too lean, IMO the sweet spot is to try to get it around 13, to 13.5.

 

I'd say you can run 14+ AFR for cruising around / part throttle, but at WOT, the mid 13 range would be ideal. A little added fuel will cool the intake charge, potentially net you more power, and add a little margin of safety.

 

Try to get the DynoJet dyno run files. I'd like to view them in WinPEP7.

As others have noted, shoot for 13-13.5.
