Timing seems low for blower setup. From what I've found is that blowers need more timing due to the increased air flow. Also, Accel enrichment and warmup enrichment seemed to be cause alot of issues for me. Definitely timing is probably what needs to be adjusted. I'm still figuring this out after 10yrs. Reply back with update.

between 20-25 seems to where should be around idle and setting the fixed timing 20 made it so much easier. There's a guy BlackFox on internet-youtube that helps out. Few others mostly on dyi megasquirt page on FB.

Boost stock timing table image didnt work out well for me. The AfterEFI class tuning worked for me the most which Scott Clark EFI Tuning Trainer / Specialist!

I am BlackFoxEFI.
I would not run any of those tables personally but each build has a different timing requirement

Just what I've tried my 2 cents ;/
Well some incorrect generalizations have been made, if it were as simple as setting the timing near 25 people would not have an issue getting idle correct.
FWIW my 393 with a blower cam and 9.5comp like to be around 16* at idle.

Your timing under boost is very low, lots of power left on the table. With a blower .75*per psi is plenty safe with most heads. Unless you are running something more efficient like a 11r, those heads and similar it's best to use an LS timing curve.
