Another thing I should add is that I can run back, to back, to back, then let it sit and heat soak, then run back to back and cannot get the IAT over 170 no matter what.

... and from all my logging to date it appears that about 10 degrees increase in ambient temperature equals about 0.5 psi loss in boost. I have logs from 45 ambient all the way up to 85 ambient and this holds pretty true.

...and that I see about 1 psi increase in boost when I spray the 100 shot. I'm guessing it cools the air, which makes it denser, which allows more room for the blower to pack more air in.
