You can usualyy hear the pinging when you floor it, although even though you dont hear it, it doesnt mean it isnt pinging.
14* with 92+ octane is fine, you have no reason to worry.
I've even had my car up to 18* with no pinging that I could hear but just to make sure, I took it down to 16*
You're ok with 14, go run the crap out of it!
