Vortec 454 Injectors

[Crussell45]

That's not the right way to do it. From the factory they already have a bit of negative trim. Going to a bigger injector can run the risk of maxxing that out, it can only trim to a certain extent. Get some LS1 injectors and have the injectors flow changed in the tune to account for it. And then enjoy everything else about the tune. You have no idea how much power is on the table with just a tune.

Question.
I have a 1998 k2500 454.
Can I put larger flow injectors in and be able to tune with the HPTuners or EFILive? No need for a 0411 swap?

The '98+ black box PCMs in these trucks are supported by HPTuners and EFILive, so yes that should be possible with no 0411 PCM swap necessary.
