from what I am told- adjusts the fuel map...headers make the car run rich...something to do with the new readings from the O2 sensors...the tune will correct this...

You need more than just a tool. Specifically, you'll need a computer (laptop preferred) and software like HP Tuners or LS Edit or EFI Live. Then there is a whole learning curve as to what you do and do not mess with and how much. I learned with HP Tuners on my '02 WS6. Since I have a laptop the software cost $500 and then it was trial and error with a lot of on line support from sites like this. Otherwise, you can have someone tune it for you for around $300-400. Good luck.

I'll definitely have a pro do the tune for me.

Boy, wide band 02's would definitely be a plus. Be sure to decide what kind of tune to you want, the biggest horsepower # or a nice big flat curve. I tend to like to tune for the street and get it like I want and then fine tune it on the dyno. This gives you the best of both worlds.

Look for a professional that has lots of experience with your type of vehicle and then use them to do your custom tune, they can do what seems like amazing things with the re-programing. Well worth the money, and the guy that I get to do the custom tunes will re-tune as many times as I need/want for free after initial fee, as long as I pay for the dyno time.

After the mods in my sig. I was running almost 10% too lean at the top end, but dead on at idle - proving the better flow of my intake/exhaust. After a couple tries and test runs we got it perfect all the way through the curve and got the A/F to a safe level. Now it's time to hit the dyno with a wide-band to fine tune things and find out my RWHP.

It adjust the fuel trims and timing mainly. It will also delete codes if you remove equipment like cats. Most cars come from the factory running rich and by leaning things out and working the wide open throttle tune you pick up some nice rwhp. I know I have seen a new Z06 gain 40 hp in a tune.
