Input on First Run, TP log pic

Finally emulated and burned a chip. I was running lean across the board and sounded way loud. Well first runs and logs all were like 148-157 sounded way loud and grizzly under the hood but idled ok in the 1000-1400 range until warm and closed loop then I guess it does surge but sound loud I am glad it is not stalling but it goes down to 750-900

I probably still can redo TPS/IAC?timing again but for S&G I tuned the fuell into it at idle and took light cruise around apartment so no real speed or load

I played with BPWvs Load first and added fuel in the RPM ranges
Question: How do I convert my AIRFLOW g/.s into load so i can see what cell I am in the BPW table I assumed I was at 16 based on the logs but probbaly off a little should

That dropped me to 144-148 range sounded much smoother could tell it was getting gas although weird smells rich i though (no cat) 165 88 LB9 auto $32b

Then I looked at my airflow. I start out at 10-11 range cold but once i hit temp I drop to 6-7 which seems normal. I think I have a vac leak that seals up as I heta up. I noticed puddle near tranny and back of engine like weeping. it is not oil gas or tranny fluid and oil/radiator fluids look clean but radiotr is low

wonder if lean condition is little bit of coolant or vac leak near rear head? intake? it can not be huge to stal or smoke out so must be intake not head?

Then I adjusted the MAF #1 and and scaled up for more fuel. For example
.9 v = 8g/s I bumped it down to 6g/s and then 1.2v 11g/s i went to 9.5 and 1.4 went from 17 to 13

this was immediate and dropped BLM into the 124 range. all in cell 16 I didnt touch 0 or 32 much and you can see they are still off.

so feedback? am I fixing a major vac leak or something or maybe injectors although all at 17ohm hot could be fully clogged or few plugs not firing.

I definitely hear a miss or two at idle.
