Correct, these are CIS-basic cars... we doan need no steekin' Lambdas!

Over on the 924 forum, the suggestion was thrown out that too-high fuel delivery pressure would cause this... and it's definitely high! I think, unless there are any other ideas out there, that we're going to try dialing this back for our next test day, put it where my car is (which was never adjusted), and see how she goes. My car was recording mid-to-low 13's for AFM on the dyno...
