This is my test run @ 22psi. I am only using HP numbers to show the butt dyno loss of power feel.

I hit peak HP by 5600rpm
HP: 334 -- Airflow 35lbs -- 22psi

by 6800 rpm
HP: 275 -- Airflow 40lbs - 20psi.

My loss of 2 psi is interesting. I always shut my pulls down at 6800 as the car feels like she is really forcing to accelerate.

my 180 was with cap off and idle for 5 mins.
On the road I am more around 190-200.

Gonna stop trying to diagnose till all my leaks are fixed. Maybe cams (272 or 280) may be in order before the stock intake manifold.
