Bolt ons & Tune ?
If I bolt on some new headers, change the air intake, etc., if I dont get the car tuned will it run like crap? Also, if you do a bolt on, say the headers, and need to wait a couple of months to do another mod, will it be ok or run chitty? Wanting to do mods, but cant afford to keep retuning after each one. Can I drive the car doing the mods and then when theyre all done, get the tune once?
Does that make sense?

I recently put on an air intake and currently waiting for my catback to get here, and dont plan on tuning it until a couple months when i'm ready to finish the exhaust with headers and x-pipe. My car drives fine.
I think if you eliminate parts like the cats and o2 sensors, you will need the tune. Otherwise it shouldn't hurt nothing.

The answer to your question is, "No, your car will NOT run like 'poop'."
As long as you install things correctly, the car is going to run fine, you will more than likely throw a code, but that depends on if you remove the air system. I have installed a few sets of headers on both my car and friends and things were fine. I drove my car around for a few months with no tune on a header install and things were okay. I will admit, that a good tune will maximize the affect headers will give you.
Hope this helps.

You don't need a tune for air intake and exhaust. You'd be wasting your money unless you do internal engine work like cam or heads.
A very reputable tuner told me as long as the exhaust tips show normal carbon the engine is fine. This came about as I was trying to schedule a $800.00 tune. He was honest and said it wasn't needed.

So headers wont need a tune? I have an 02 Z, so I was thinking of leaving the intake alone, but the headers I'd like. A cat back isnt something I'd want either. I feel the stock Ti is fine.

The car will run fine, I drove my car for a year with headers, intake and no tune...since I knew I was going to do heads/cam package the follwoing year and tune then. The car will throw a cat code, but it won't effect the performance in the sense it will run crappy. Getting the Tune will help you get more performance out of the mods you put on. The only other thing to consider is passing emissions in your state (if you have emissions)...most states if you throw a code you will fail emmissions, but again depends on the state.

You will need a tune if you wish to maximize the additional hp headers will give you. You don't need it in the sense that you will otherwise hurt the car.

If you want to maximize the effects of the headers, then get the tune. But you can drive it around for a while with no adverse effects.

I have headers, intake ,exhaust and the car was tuned(July '06). I took it in for warranty work this past Thursday and the dealer reflashed my computer, taking out the custom tune. The car is running fine now, but I definitely notice the difference without the tune. Monday I am having the tuner(Doug @ LAPD) put back in the tune. When you get the chance, I would tune it. Hopefully I will soon put in heads and a cam and will have Doug retune for the new mods. Tuning a car is worth it as I saw a brand new stock Z06 get about 25 extra ponies on Thursday.
