I'm going to gather up all the info that we need as far as air flow / aproximate fuel pressure & what not & the shape of the intake manifold & i'm going to bring it to a physics professor & see if he can tell us which cylinder whould be running most lean based on all the fax. I'll make sure i get back to you on that tho WCS because i'm very interested in finding this out as well & i'm sure if we want to know.. then there are others out there looking for the same information!
