Thanks. Would liked the external waste gate "chatter" but think I'd need to fork out another turbo

You can always shut of the internal one.
Or run both.
It will all work.

I due urge you to block of the original wastegate and use the external one.

Can the original one be welded closed or can you buy a means to cover over it?

either is possible,
Here a couple of flats have been welded to keep the gate shut.

Here is a flat plate that covers the wastegate
Then you drill a hole where the wastegate flapper is, thread it and put in a bolt that keeps it shut.
