What to do first?
If it's an automatic, a higher stall torque converter should be a priority. If it's a pre-01, a ls6 intake would also be up there.
headers/exhaust
stall
sticky tire (555r would be good)
tune
Would make for a very healthy ride. If short on funds, I would pool all the money into a quality 3600 converter (even a good used Yank, Circle D, Vig, etc) and put better tires on after the current ones are burnt to a crisp from the new awesomeness.
Is this your daily driver/street duty only, street/strip car, mostly drag etc.?This will also help on advice. I agree with Thunderstruck. You already have the LS6 intake, stall is next bang for buck mod.(3200-3600 for street/strip).
Then LT headers, P&P TB, suspension mods, etc.
See...we need more info and budget.

Seems like a waste of $400 to me. Wouldn't you wanna wait for the tune after HCI? I was planning to probably do a lid.. eventually.. but I wasn't gonna bother with a tune till I get a new engine or something.
I agree tho.. with one exception. Do a tune up THEN do lid/exhaust.
Oil change, plugs, wires, clean the TB, IAC, MAF, new fuel filter new oil filter new air filter, check the brakes.
I have a feeling this is a DD for you?
Ls engines can get a really gunked up TB over the years because of the EGR.

For a bolt on car I would get a mail order from Frost though. Headers without a tune is throwing away about half the HP gain they give you.

I guess if you don't plan to do those things, or you're unsure if you plan to, that does make more sense. I hadn't thought of it that way.
