i will be swapping in a ls6 intake and a ported throttle body on my 00 Z28 and i was considering putting the 01/02 injectors in while i was there. i am not sure if it is worth it to do this at this time or not. i am a full bolt on car right now, with stock internals. would it need a good tune with the change of these injectors?

01-02 injectors are bigger but as far as the tune I wouldnt think so I did it on my 98 with stock tune.

your 98 also has the larger injectors in it though. 98, 01, and 02 have the larger injectors.

Yes, you need to copy the 28lb. IFR table to your tune. I swapped injectors after my intake install because my fuel trims (+12-15%) and duty cycle (92%) were high. The 28lb. injectors brought things back into line.
