TDCI Injector Upgrades?

[gzarych_mk6]

Hi everyone. I have a 56' 1.4 TDCI fiesta. I have already had it mapped, exhaust ect. Would any bigger injectors from fiestas or focus be worth fitting?

Not really, there's a hard limit in relation to how much you can squeeze out of that engine (purely in mechanical terms, let alone whether spending further £££ on 2006 MK6 make financial sense).  That engine was design to efficient (relatively speaking) when it launched, it was never designed/intended to have an increased output which is why it wasn't fitted to something bigger i.e. MK2 Focus etc.
