It's only a small difference but a bit of headroom is never a bad thing, depending on what fuel you were mapped on and what your using at the time it could mean the difference between detonating and not.

Just want to be safe....
when your getting those sort of results then why not be safe, I bet with lowish egts and AFRs you could lean it off and make a bit more power though- always running a bit of risk on a cold day then though.....

Exactly mate we just want reliable power, not a car thats on the edge of breaking all the time! lol
IMO without monitoring EGT's or running a knock sensor anything over 12.0:1 is a bit too lean on a RST.......... but each to their own
