ITB Synchrometer (Syncrometer)

I picked up a Synchrometer from a local Motorsport business, Dirt Devil Ind., just located 30mins from Brisbane. It's used to tune/sync ITBs or carburetors for a smoother idle and acceleration. It's not really necessary but why not hey?

It works by measuring air flow through the trumpet (velocity stacks). The synchrometer has a tapered rubber tip that inserts into the ITB opening, than using the bypass adjust screw to set each throttle body for the right amount of air flow at idle.
