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.

It's a borrowed factory WUR so it's not adjustable. I'm still waiting on my Brian Leask Adj one to be finished and shipped back.

Good info! The low 11s is when boost starts all the way through the rpm range. I mean it bounces around a little but it stays between 11-11.3 steadily. I'll leave the setting where they are now and just enjoy until mine comes in and then check it again and dial it in better if necessary. It does idle smooth now and overall runs and feels great.

Sounding good. Just wondering, do your exhaust manifolds glow at night? Just idling in the driveway after it has been driven.

I really don't know because I honestly can't remember the last time I drove this car in the dark. Maybe a boosted midnight run is just what it needs?
