Some vehicles do not run very well at all (if even drivable) with the accel enrichments turned off so you are not alone.

You could just tweak your VE to make up for the lean spike, but this would only work if the second butterfly is triggered by MAP, not TPS as you described.

I don't run MS2 and ...

The second picture of your first post didn't load for me the first time. Now it did along with your new picture.

Looks to me like it's a VR wheel.

Would help if you pulled the rotor off so we can get a better look.

But if the tips of that star pattern is your trigger wheel, it would be a VR sensor.

I was focussing moreso on the boost/upper rpm area for the pinging issue.

Yes, idling at 13.0 is fine. That's around where mine is and I've never had trouble with plugs fouling.

Idle isn't meant for fuel economy. You'll have to deal with a seeking idle if you want it leaner as some motors don't like to idle any leaner than 13.0-13.5.

Sorry, I mis-read the 58* as highest spark table value, not your trigger angle.

That map looks alright for a normally boosted motor.

Where did you get 58* from? Maybe you should post your spark map for us to get a better look?

My point before was that 58* is very high for any NA motor let alone a boosted one.

I agree that a small 0.5 AFR is nothing to complain about.

I have never put an NA motor past the upper 40's for timing and that's at high rpm midrange map values.

I don't know your motor, but I would suggest that if it's actually 58* then you probably want to retard it considerably for peak power as well as getting rid of the pinging.
