with your impressive turbo numbers I would
imagine you are maxing out the MAF at even lower revs.
‘Dr Greg’ in Aussie did custom MAF for his modified supercharged XJR, which had about 600 bhp. I don’t k ow the details, but you might be able to track him down.

Andy Stodart has previously stated, and I paraphrase, that the XJR fuel map is rich, so exceeding MAF limit will lean out the mixture which should be OK for short bursts..

I think the attached article is about the Dr Gregs car, that gives some information about the setup he was running

i wonder if one of the commonly available lucas 42lb injectors would be an acceptable substitute

There is also this D3165BA that might be usable, page has also dimensional drawing

@AnttiM Thanks for sharing that article- I read it 3 times! That level of detail truly raises the bar and makes my effort look like it was done in a home garage by person who doesn't make his living working on cars- it was! Now you've really got my brain working overtime... Twin turbos? @XJRengineer would agree that the cam specs on the AJ16 make this car the perfect candidate for twin turbos.

Have a good evening.
