Looking to upgrade 99 pcm

I have a 99 2500 Silverado with a LQ4, I'm looking at getting a 02+ pcm. What else do i need to do? I read that i have to upgrade the injectors if so what one to get?

Thanks,

Tom

Why not just get a tune on the one you have.I have no problems with tuning my 99.

I changed to a 2002 because my 99 was giving me a lot of false knock problems. All you need is a tune and its plug and play, as long as its from a cable throttle body truck.
