If i upgrade to 30lbs/hr. or 32lbs/hr. do i also need to up the pressure range on the regulator? (LT1, stock pump) do i need to upgrade the pump too?

Injector upgrades do not require a different pump or fuel pressure regulator, however, they will require PCM tuning. Is there a reason that you are upgrading to the bigger injectors, have you done some recent modifications to require them?

yes, there are many things in the works, and i do know that with the injector change i will need to also have the PCM retuned, severely

I have some 30# injectors that have less than 150 miles on them. I have a supercharged lt1 and it wasnt enough injector for the boost. So needless to say I need a bigger injector and will be selling these if your interested.

Thanks,

I went with 42's for my setup to allow for room to grow. Let us know what you plan to do right away we can figure the size that best suits you. This should also include future plans.
