Well i think i've figured this out for the most part. Other MS users have had lean start issues, and i've figured out that the air density correction algorithm was not adding enough fuel for rising intake air temps. It was pretty clear just by watching my intake temps rise, and then watching the o2 correction add in more fuel as air got hotter, esp when going above 95 degrees, and really bad when in the low 100's.

The new alpha test code i'm using is 029o, which has air density correction table in it. YOu can choose either coolant correction, or intake air temp correction. It seemed to work quite well so far, and i'm only really using the correction at idle and slightly above, which is when intake air temps can get hotter with the slow air flow, and a large intercooler. When intake temps were around 150 on a hot restart, i needed approx 30% more fuel to keep the o2 correction close to 100%.

So there it is, if anyone has this issue, just try out the new alpha code and see what happens. The car idled the best so far with this code version as well. Very smooth.

One more issue that i figured out was the hunting idle, and roughness, was my PCV valve was sometimes letting air by, and sometimes not, which was messing with the idle speed, and fluctuating the MAP signal, which was messing with the smoothness of the idle. So i just took that out, capped off the intake port, and ran a line from the fitting on the valve cover to my catch can. It's working great so far.
