I have a temp sensor just behind the throttle body as a consequence of 
the EFI system, so I have an idea that the inlet temps are not as bad as 
I originally thought.   Then again, I may not have an accurate temp 
sensor (I'm not convinced of this part's accuracy and response time yet - 
I'm looking into a better one) and I'm only running 14psi currently, 
which is below the turbo's peak efficiency from what I understand from Scott.

I have to think about this for a minute, but doesn't temperature and
pressure completely define the density of a gas in terms of variables? 
Bob Myers?  PV=nRT  so I think so.

I guess humidity would lower the oxygen density, which would make the 
charge less efficient.

Next time I get a few minutes to actually tinker with my car, I'll toss 
in a couple thermocouples, and put this one to bed, at least in my
