I would look at the plumbing, the vaccum pipe that runs to the dump valve need to goto a good vacuum point, ie on the inlet manifold and check the dump valve is actually closing properly and has no air leaks.

you dont quote what dump valve you have as Bailey did a few different types, but like the old rs turbos, scoobs prefer the twin piston dump valve type.

what you say is typical of the older style dump valves, as the engine goes to cut out, the vacuum level increases and opens the dump valve, which then increases the revs and so starts the surging or unsettled idle you mention.

I have a bailey twin piston one on mine and it works ok, I have also had a few forge ones and they have been fine, but i found with experience a good vacuuum pipe from the manifold works the best ! ( Ihad a few blanked off pipes on mine i connected to )
