How do I do away with the EGR in the chip?

I am changing from 19# injectors to 24#.
What is the difference in single fire and double fire? Does doth single and double need in the ECU? If not which do I use?
I have the 165 ecm.
Thanks for the help.

Set the enable temperature to a high value.

Single fire is when the injectors fire once every compression stroke (every two revolutions). Double fire is when the injectors fire twice every compression stroke. Double fire is the normal mode. Single fire is used when the PW gets too small for double fire.
