However, if in fact all of the airflow is not going inside the engine, this would definitely cause a really rich mixture. This is just something to check, I'm not 100%sure without being there to see it myself. Check to make sure all of the vacuum lines going to the bypass valve (black round thing on the right side of the blower) look to be secured. Start the engine and listen for any vacuum leaks around there -if there is a vacuum leak you should here a suction noise. It is worth a shot before you have to go to Magnuson.
Flyer: hey man! Here is a good page to bookmark for conversion http://www.bizinfogrp.com/unitofmea.html
The conversion from lb/min to g/s multiply by 7.560
For g/s to lb/min multiply by 0.1323
(off subject a little here) Flyer, there is a guy on here, 954RR who runs a Radix and a .212/.218 .522/.529 114lsa cam. Ask him how it runs man.
Oh ya, Fun Guy AutoTap is a program that used with a laptop reads all of the outputs of the sensors on the powertrain computer. It is like the TechII scanner you mentioned before. Here is their website though http://www.autotap.com/

By the way I would like to know what someone with the same cam has as far as idle rpms. Mine really doesn't lope at an idle but it does idle around 900rpms. I think it is so high to prevent it from surging in gear.
