13.5@ idle is perfect, it should idle very smooth there.

Low 11's under boost doesn't say anything unless you say what rpms that was at, and high 14's or even 15:1 at steady cruise will give much better gas mileage than 13's.
If the control pressure regulator is not a Brian Leask modified adjustable one there's nothing you can do about the steady cruise control pressure and afr's without leaning out the idle afr with the CO adjustment 3mm allen head more than you want.

You could lean out the idle CO to get 14-14.5:1 idle afr and idle will still be good enough just not as smooth depending on cam duration and timing, and cruise afr will lean out at the same time. Boost AFR will stay the same.
