As above get the cat nice and hot before mot , other than that looks like you will need new cat or you might have a faulty injector, are all plugs the same condition, is air filter clean.

You can,t adjust the injectors might be a dodgy injector but could still be cat , did you check the plugs ? so you have had the ecu read but no faults stored ?

lol at 'turning up the injector' they are only operate on an "on"or "off" state, you can make them stay open longer, but not on standard management.
High VOC's usually mean you aren't burning the fuel so has nothing to do with the CAT or lamda sensor. Try ensuring you have a spark from all 4 plugs. That is the most common cause. If you touch them to your tongue and turn the starter over and you feel a little shock then it is ok  if not you need new leads or coil.
I would rather lose by a mile because i built my own car, than win by an inch because someone else built it for me.
