Finally got a chance to run a few WOT tests today and I was getting wide band readings in the 10.5 to 10.7 range @ 6200 and 15 lbs boost. Keep in mind I am testing with a full exhaust and 5000 feet above sea level. Still way fat - I would think? I will try going back to original jetting ( as I got the carb from Pro Systems ) and see if that will lean it up a bit. Pretty sure that is where my short plug longevity problem is coming from also. - - lead fouled.
