What year is the vehicle 1988-91ish?
Given what you are refering to is a non-standard engine the MoT inspection manual should have a decision tree chart with yes/no options.
I know for passenger cars 1st August 1992- 31st August 2002 that a turboed engine such as yours would require the tester to perform a non CAT test because the tester will be unable to find an EXACT match in the analyser database
CO<= 3.5%
HC<= 1200ppm
I would imagine your engine will have to fulfill rather similar requirements.
If you need, PM me an email address and I will send you the relevant info I have - you could then use that to go to a local tester and ask them to show you the corresponding page for your car.

Mosselman spec is 1.3 - 1.7% C.O. @ 650-700 RPM idle speed.
The Mosselman enrichment electronics have no impact on the CIS-E at idle or no boost conditions.

Would you happen to have the HC figures to hand too? His car (if in the UK) will get tested for them as well

I believe the CO numbers were for a non catalyst car.
They never published the HC figures but I can give you a real world example.
My 1988 300CE M103-12V with a TurboTechnics twin turbo install with two ( one for each turbo ) Magnaflow spun metal high flow cats tested at idle: CO=.43 HC= 100PPM.
Basically the TurboTechnics or Mosselman at idle performs as stock.
If the basic CIS-E is up to spec then the test should be the same as a well tuned NA engine.
