It got new plugs and wires three days ago, The old ones had this light brown coating all over them and were gapped too wide. New AC-Delco plugs @ 0.60 installed.
The Fuel pressure went from 38 at idle to 42 when i removed the vacuum line from it.
The latest scan is uploaded www.damemorder.com/scan/

Would your friend mind getting the new TB on his car?
Secondary thoughts:
On this run the IAT was picking up really hot air, which should negatively affect the MAF reading (hence power) BUT the reading this time was actually ~800gr/sec HIGHER at its peak reading.
Averaging out your spark advance at WOT your old reading was 20.2 while this one was 21.7, and much smoother and consistent. Could just be the pump is acting right for a second though...
Your coolant temp was considerably colder also...

My UIM only lost a little peice, Making it leak coolant... if there was no coolant there to leak, Problem solved. And I mean tapping a plugging the holes on the LIM side, it'* solid aluminum.
