Kevin V 2002 SS

I'm putting in a TR224 cam and TEA Stage 1.5 5.3L heads that have been ported and polished, with 2.055" intake valves. I already have the PPC LT's with the RT hi-flo cats.

I know there are supposedly some things that need to be edited for the computer from the start after the install. Can anyone help me out with what needs to be edited and why, the engineer in me likes to know as mush as I can about everything.

Thanks!!!
