Under the bonnet to the right of the yellow aircon label there is a label with loads of different models on the one for your vehicle will have two values 1.14 for manuals and 1.18 for autos.
Cover this up these values, if the Mot tester can see them he will use them if he cant he will use the standard 2.5 value yours will have then passed its mot.
MOT inspectors are not allowed to remove anything and it's not an advisory or failure if covered or removed

Injector number 6 replaced with a refurb and white smoke at idle is no more. It was very rusty and obviously in a bad way. It has now passed its mot emissions test.

However, as expected the other injectors are way out of balance. I am now getting:

1. 869
2. 1198
3. 1323
4. 1244
5. 1398
6. 601

With errors:

Cylinder 6 balance - fuel trim at minimum limit.
Cylinder 3 balance - fuel trim at maximum limit.
Cylinder 2 balance - fuel trim at maximum limit.

I suspect I am going to end up changing at least 2 more injectors.
