2 questions ?
I have 2 questions and need your input.
1st ? , what modification can I do that will give me the most bang for the buck? I am bone stock with a K&N filter.
2nd ? I have a chance to buy a seperate set of tires and wheels, will it mess up my sensor readings if I put on another set of tires/wheels ?
I can buy them for $350 and really want to use them to go to the track and fry them making passes at the track, as I don't want to fry my new run flats.
Thanks for your help.

Bang for the buck - do you mean more power out of the "hole"? You don't say whether you have a MN6 or an A4 - but assuming you have an A4 - probably the best bang for your buck would be to install either a 3.42 or a 3.73 rear gear and get a dyno tune. If you have an MN6 - either a 3.90 or a 4.10 gear set and a dyno tune.

If you are replacing wheels and tires for the track only - don't worry about the sensors in the O.E.M. wheels. Just press reset on your DIC when you see the message "SERVICE TIRE MON SYS".

Question #1 depends on how much buck you have and want to spend
most people do start out modding by changing the air-intake and cat-back exauhst..but it will not give you any big HP increase, exauhst for sound, and air-intake will help your throttle response.
Question#2- you can switch tires/rims, it won't hurty anything with your sensors... they might loose sync with your cars computer, but they are very easy to re-program and the instructions are here on the forum.. lot's of guys swap tires for the track, some even have track tires with sensors.
You will probably get an error message on your DIC that says "service tire system etc.." but it's not doing any harm to anything.

There is an old speed shop axiom: Speed costs money; how fast do you want to go?
As mentioned, the common first mods are an intake system and a cat-back exhaust. Find a good tuner and get a performance tune done.
Gears will give you the feel of a performance mod as lower gears (higher numerically) offer a torque multiplication. The engine revs quicker and you accelerate faster. You may lose speed at the top end but going this way depends on what you want from the car.
The tire pressure monitoring system will give you an error message if you install aftermarket wheels but just hit the reset button. Are the tires and wheels the same size as the OEM tires/wheels? Going too far away from original sizes can cause issues with ABS and Active Handling. The PCM looks at wheel speed and values beyond what it expects can cause problems. You can also get incorrect speedometer readings it the tires are too large or too small.

oppps! Its a 98 Auto. I am looking for "go light to go light" HP and want to spend < $600 
I want to improve 1/4 mile performance with out going nuts.
One of my friends has a 5 psi Blower which he replaced with a 15 psi blower , he said I could have it for -0-. His '00 sounds like its coming apart, in a good way, Turning 715 rwhp. It is almost too much
The tires are off a C5 Corvette , but the guy has them on a camaro. They are in decent shape and all I would really do is put the rear tires on. Not much need to swap the front ones for going to the local track?
