Rick, I checked the air bleeds and they are all clear. The plugs read well except one was dark, but when I put it back in it broke in half so it may have been cracked.
A miss can mess up the wide band reading because you now have unburned fuel and excess oxygen in the exhaust even when the mixture is correct. It's possibly going to show lean rather than rich.
On the vent tube extensions, they are always a good idea, especially if you run a hood scoop. As for jet extensions, you need them in the rear if the vehicle accelerates hard enough to push the fuel back in the bowl. This probably isn't happening on a street driven car like yours. I would think you'd need to have 60' times around 1.25 sec (or the potential for that) to need the extensions. Also the small extensions that fit in the counterbore of the jet are not my preferred way, rather I use a piece of 3/8" steel fuel line, and a plastic float that's either made with notches for the extensions or home done notches with epoxy to seal up the notch.
Your time starts when your front tires clear beam.
In addition, I remove the rear piss whistle if so equipped, if a car launches hard it can cause issues.

I have no clue whatsoever as to what a rear piss whistle is. I even googled it and learned that piss whistling is a practice of making a horse piss on command (with a certain frequency whistle). Less weight for racing. I just can't make the connection?
Do all times start then?
