https://raytechautomotive.com/ Has anyone tried these ? I have wanted an air to fuel measuring tool, good to see an Aussie product out there that isn't stupidly priced.
They also do a 4 pot vacuum balancing tool that is all electronic.. well priced too... from everything I have read they are very good products. https://raytechautomotive.com/produ...burettor-throttle-valve-balancer-synchronizer
