newbie here, with tuning questions

Hey guys. Just found this site and it seems to have a wealth of information on it.

Anyway, to get to the point, I don't own an F body. My buddy does though, and he knows practically nothing about cars so I am his "go to" guy when it comes to questions. Anyway, he just blew his engine in his '98 Z28, and found a reputable engine builder to rebuild it. He wanted something a little faster than stock, so I suggested he go with some of the mods listed in the "LS1 cookbook" article that appeared in Hot Rod a few months ago. We've decided to go with the Comp Cam xr289, Comp Cams' 1.85:1 roller rocker kit, Comp Cams' beehive valvesprings, long tube headers, and a .030 overbore.

It's obvious he's going to need a custom tune with these mods. I'm not familiar with any of the methods used to tune a car (I'm a motorcycle guy). Here's my question: Does he need to buy a tuner, or can he take it to a shop with a dyno and have them re-program his stock ECU for his mods? He is in Jacksonville, FL. If anyone knows of a good shop in North Florida that can tune an LS1, please let me know.

first thing i see is the .030" over bore. not going to happen. the most you'll get is .010". easiest thing would be to take it to a local shop and have it tuned by someone with experience.
