What is the most important gauge to have in your line of sight, A/F meter or boost? I know it is important that you don't have boost creep, but isn't boost creep ok if the a/f is adequate? So as long as the motor does not run lean, which an a/f can detect, a/f is more important for the life of the motor?

 

I don't think boost creep is a problem at all as long as it doesn't creep past your limit. A/F seems to be important at all times, lean is bad as you know.
