yea, i just have to take some time to think about things.

thats what i figured, once open the exhaust pressure is no longer an issue.

now my next questions are is the boost pressure the same above the throttle plate as it is below the plate at part throttle.
with my control pressure at 3bar and my AFR at 14.4 at 2500 rpm, am i causing my slight miss?
will it go very lean again if i raise the CP?
this AFM acts or reacts a lot differently to mixture adjustments than my 77s did. its taking some getting use to.
what i have been mulling over as far as the AFM is that with the lower pressure, the plate will be further into the "cone" at 2500 and even though the CP is lower, the plate may not be moving enough to provide the proper mixture. even though the CP has rich end the mixture, how much has the mixture screw compensated for that since i would have to lean it back out enough at idle to get 12.5 far.
