I can't think of any. IIRC, the "T" injectors are set to a higher POP, not sure if the nozzles are any different. Remember, it is the IP that sends the measured fuel spurt to the injector, so a different injector can't really inject any more fuel into a combustion chamber than what it receives from the IP.
Of more importance is that the injectors are:
- All set to the correct POP, and not widely varying from each other.
- Good atomized spray pattern
- No drips or moisture when held just under POP for 10 seconds.
