Annular boosters on a Tunnel Ram

So, question then, I would be able to try the "wire test", thin wire inserted into the MAB to reduce the size quickly and easily to see if it gets better or worse as I don't have a dyno, data logger, or O² sensors, yes? This would tell me if the bleed needs to be smaller (later to start and richer at WOT) or larger depending on how the car reacted. This would also then tell me why it worked better vs it just did.
Yup, that’s exactly what the wire test does. Just make sure to pinch the wire under the air cleaner lid so it doesn’t get pulled in the engine.
