Is it safe to do machine work like on the heads and intake without messin up anything with the computer, and is it safe to run headers

well depends on how much you do. ported and polished intakes will be ok.

What kind of head work you thinking about doing?

Yes, headers are perfectly safe. I have them on my stock PCM

Yeh... the 3.4 certainly has some room to modify before ever having to change the pcm or it's tune.

Hot heads and a set of headers will run just fine on a stock tune.

well thats good cause i got my heads lookin like the ones in the picture of the 3.4l specs and been workin on the intakes, and ive been lookin at the pacesetter headers and they all say w/o air, does that mean you cant use air, its hot in Georga, and i damn sure dont want the stock manifolds on it
