Hello my friends!
I have a few questions to ask (I'm sorry, I have no knowledge in polish, only english or russian)

Nozzle upgrades are very common for Volkswagen/Audi TDI engine upgrades when more fueling is needed (when upgrading to larger turbocharger)

Let's take BMW 330D injectors from M57N 204hp engine as an example. They are approx the same in flow rates as earlier M57 injectors from 530D/330D 184hp.
They have 100% same internal parts and external dimensions as BMW 535D biturbo 272hp injectors (which flows about 50% more than 330D injectors), except the nozzles, which have different part numbers.
It's common upgrade for M57N single turbo engine to replace injectors with ones from 535D so after chiptuning one can get more than 300hp.

Then there's the question: Is it possible to just upgrade BMW 330D injectors with bigger 535D nozzles (they will 100% physically fit inside injectors and is driven by the same valve mechanism)?

Who can do IMA coding after nozzles are replaced and will injectors flow the same as OEM 535D injectors?
