aan injectors on 3b engine with mrc stage 1 chip

[Pirvu, Eugen HRO]

Hello!
Sorry for this question but I really don't know if is ok to change the
3b injectors with the aan injectors if I have the stage 1 chip from MRC.
I have these injectors with 4 hole but I don't know if this change will
be an improvement or not. If is an improvement, please tell me how to
do. Is necessary to change also the pressure regulator? If yes what
pressure regulator should I use to fit the 3b fuel lines?
Thank you very much!
Marry Christmas and Happy New Year!
All the best!
Eugen
