Probalby pretty close you could try backing the fuel pressure down a little but if you have already tuned your FMU for that fuel pressure i would leave it alone. 42 is the stock fuel pressure setting for the busa 1 lb wont make that big of a difference but 12.8 aint bad at idle for the stock ECU and the cams the busa has in them.

ya you are close to good
i like to see mine a little leaner at idle if i am planning on tunning it
i like 13.5:1 at idle
and i run my idle just a little lower on the FP but tony is right if its good then keep it

I actually like mine a little richer at idle.  Richer runs cooler.  When are we at idle??  HMMMMMMM  Oh Yeah, in STOP & GO Traffic!!!!  What also happens in STOP & GO riding???  You guessed it, over-heating...  So what will help that problem we have all struggled with?!?!?!?  You guessed it, run it a little richer!!!!!
