PCM sometimes pulls timing but can't for what reason.
1999 trans am running speed density sometimes the car will pull timing but can't find any reason why it should. I've been told that I should have my low and high octane tables the same. Also have heard there are calculations and tables not seen that affect timing.
Any thoughts?

don't think it's burst knock, don't see any kr, it's like it's going between unknown tables and calculations doesn't show anything in the datalogs.

That's about all I can come up with off the top of my head without seeing your tune.

You still run a MAF? (nevermind I see you don't) VE table looks bonkers. Injector data, Engine Size, Cylinder Vol looks wrong. Injectors will not flow the same volume when intake vacuum changes and it uses the Cylinder Vol to calculate along with your injector data for the VE table. VE table should look like a dyno sheet and not the ocean.
Why is Boost Enrichment Enabled at 110 kPa but is set to 1.00 all the way across? I know it will use your PE EQ ratio table as it's richer.
I know this doesn't help your problem but I wouldn't go into PE until you address those issues. Do you use a wideband? If so go drive around and get a log and post it up.
Try putting the MAF codes to 2 instead of 3. Maybe your car is different but when I put mine to 3 the car will not run right.
