Just leak tested the car, and it's leaking pretty bad in a couple spots.

Of course the analytical scientist in me had to analyze the data I generated on the dyno and forecast what my boost should have been.... so a little Excel and I have this...
As you can see, my boost was pretty smooth and linear till about 4800-5000 rpm then it became a mess, which from playing with the pressure on the air compressor, sounds about right. When I turned it up to about 14-15psi is when the air just starts blowing out of both the iat sensor and the bypass valve really loudly.

The leak out the air temp sensor wouldnt make any difference, in the overall scheme of things it would be tiny.
The valve could well be a different story though. And because your test cant take account of pressure drop vs flow across the intercooler core....good chance you have less pressure holding it shut in normal use, than you would do with a static test.
So it probably leaks more.

Also check the volute on the Procharger and make sure it is not leaking thru any of the bolt holes that you are NOT using. You should have set screws (Allen screws with no heads) screwed into those holes to prevent boost leaks.
When you pressure up your system, soapy water the head unit and look for leaks. You'll definitely find some. Slight as they may be, there will be leaks. Mine leaks slightly between the volute and gear case. Also check your blow off valve. Even with pressure applied to the top side of the valve, my original Procharger BOV leaked some.
Once again, probably nothing measurable but... I'll take what I can get.

I used a stock IAT sensor from a turbo buick grand national. I had a welded bung on my charge tube just before the throttle body. That was done previously by the person I bought it from. Never had an issue. Also if the sensor ever goes bad, it's easy to find a replacement.

Exactly. The way I look at it, is if the blower is working to move the air, it should be ingested by the motor to make power. It's not like in a turbo setup where you chose how much boost you want to make and then push out the rest, I'm greedy, I want every last cfm of air to go into the cylinders to make power.
