I’d say around 17 bar on a hobby type tester and nor more than 10% variance between cylinders. Test when hot with throttle wide open, disconnect the injectors and remove all the plugs.

Thanks fo that Dave its appreciated. D Tech motorsport here in NZ are installing an Emerald but having a few difficulties. They hace spoken with a member of your team back there in Blighty apparently? They just wanted to carry out a compression test to get a few figures.
