Ya. I'm worried about that. It runs in closed loop only 
at idle, where it corrects via the 02 sensor. I'm 
worried that is will be real rich since i can 
compensate the AMM but not the O2. A megasquirt and an 
MSD seem like the most flexible and best bang/buck 
option.

Well there's no flapper, just a hot wire. But I know 
what you mean. It could go full scale voltage wise at 
200hp worth of airflow or something which would suck.

Sweet. I live hearing stories about people running 8+ 
psi with that kind of compression ratio. Encouraging 
for my project. How are you set up intercooling/water 
injection wise?
