looking for tuning guidance

May I suggest that you run a fuel pressure meter to the inside so that you can see what it is doing under hard acceleration?
The Manifold Air Temperature and O2 sensors also affect air/fuel ratios.
Oops! I forgot about the Manifold Air Pressure sensor.

I'll do that. I threw my old chip back in while I figure this out. It runs fine on the sinister tune, just a little off.....  i know the factory ve tables are MUCH lower than what is on the sinister chip.

Check the Base Pulse Constant (I think it's called.) It's in one of the first menus. It's a two-dimensional slider, based upon displacement and injector size, among other things. (Been a long time. I don't remember the formula.)
It affects all of the fueling. If it's the same in both chips, the lower VE tables will truly indicate less fuel. If it's significantly larger, then the lower VE tables will tend to cancel it out. (Not really correctly, I don't think, but it kind of works out that way.) Just more to add to the confusion.

Sooooooo, what you're saying is, bigger is better?

That's "The First Rule..." "If 'more' is enough, then 'too much' is just right"

Raydar,
I found two problems that held back fueling.
Maximum asynch bpw was set to 5ish. It needed 9ish to spray enough fuel.
Second, as suspected,.the fueling tables where 10% too low at600-800rpm, then 20%+ at 4000 rpm.
Its still lean at the higher rpms and I'm still tinkering with it. 
Otherwise, the factory fueling curve seems to feel better than the one sinister, based off a Firebird 3.1, had provided.
......to be continued......

Cool. Thanks for sharing. I never messed much with async settings, I don't think.
I'm learning something...
