Default what size injectors?

What would most likely be the maximum size injector I could go with while staying with a stock turbo and edge turned up all the way and not have issues with too much fuel and not having high egts? I was thinking 80s would probaqbly be about the limit before upgrades are needed with a turbo?

Thats cooler than what I would have thought, but I guess we can hit 1200 fairly easy with the comp and 65's pulling heavy up a steep grade, sure runs good and just smokes a little, ok maybe 110's arent out of the question.

Idk its up to you what you want but I like my truck with the 110 injectors in it. It smokes the way I want it to if I want to show off and it pulls anything that hooks up to it.
