How much timing ?
Just curious,
How much total timing are you guys running.
I am:
30* at 12# with 50/50 (91)gasoline and 110
have run on just 91 but feal better with some 110
No issues

At the moment I'm at 23.91 degrees above 4800 rpm with 7 lbs. of boost on 93 octane.
My spark table dips down to 20 degress between 3600-4000 rpm since I seem to pick up knocks there and ramps back up to 24.

My car was tuned at 27* with 6*btm on 93, but i have bumped it up to 8*btm so 29* and running on a 50/50 of 93/100 both sold at a local sunoco. Havent had a chance to get it to the track or have it retuned since the new heads and intake were put on so not sure how much it gained from it.

I run 21° at 25+ psi, but at mild boost levels, the timing is still in the very high 20°s. A lot depends on the cam and head selection, but many tuners tend to be conservative on timing to ensure there are no knock problems.
