"Wheel Spin" or lack there of!!
I just bought my dream car! A 2002 Coupe with Corsa Pace Car Exhaust and a SLP Blackwing air filter. I had to buy an Automatic since I am 6'7" and letting the clutch out would be like performing a gymnastics move every shift. I am extremely happy with the car but have noticed a few issues.
The first issue that concerns me is that off the line acceleration feels somewhat sluggish. I can punch the throttle and the car seems to slowly lurch to its full potential. This leads me to my other question. Why in a car with 350+ HP can I not spin the wheels? Am I that fat I weigh the back end down? I turn traction control off and punch the accelerator yet I never break loose.
Another strange occurrence is when at WOT and the car shifts there is a loud sound coming out of the back. The best way to describe it is having 300 baseball cards on a bike while the bike tire is going 60mph. It happens under hard acceleration and seems somewhat alarming. I have been told that the H pipe is causing this sound due to the restriction and that I should purchase an X-pipe.
Does anyone have any hints as to what might be wrong? Also, if this is normal does anyone have any suggestions on getting immediate power to the pavement?

What is the rear axle ratio? A change in gears will certainly give you a quicker response.
No idea about the sound - I never heard anything like with my H-pipe nor my X-pipe.

The car has 10" wide tires with positive traction and 18" wheels. It's not going to spin like a 14" tire on a non posi rear. If you have the 2:73 rear, that also cuts it down. The 3:15 is quicker. I personally like the fact that while the other guy is spinning his tires and burning off rubber, I'm on down the road.
Having said all that, it will certainly spin the tires if you want to. There are lots of things you can do, I'm sure you'll get lots of advice from others here.

With the traction control off or in Competitive Driving mode I found that I need to floor the accellerator extremely fast to get the tires to spin. If I floor it at any other speed the car just squats and goes with very little wheelspin.
Now that I think about it this is probably a good thing.

Just try power breaking with the traction control off!
Hold the brake moderately with your left foot, and as you rev it up in drive, you will feel it wanting top break loose.
As it starts to spin, let off of the brake more.
You should be smiling by that time!

Jason@EnglandGreen has a 2.73 automatic, and bone stock it would smoke the tyres for 100 feet at will.
My own 2.73 automatic - even after a cam install making 385rwhp - absolutely refused to spin the wheels. Ever.
Went to 3.90s and a 3600 stall and there was zero traction.
I preferred zero traction

Like you I was a little disappointed when my new 04 coupe would not spin the tires. Spinning the tires with out power braking was always my personal benchmark for a "Real Car" 
. I changed out the 2.73 gears with 3.42 gears and it was a real improvement. Remember, we are losing almost 70 HP through the drive train with the auto so the 350HP is closer to 280 at the rear wheels. Finally I added a Yank 3600 converter and now I can spin the wheels any time I want. If your vette is a DD I would suggest 3.42 gears and a 3200 stall converter. You will need new rear tires ofter though,

I think this is why, on the '02 cars, the A4 was listed as having 350 lb-ft of torque, while the M6 lists 375 lb-ft.
If you turn it off altogether, you should probably start budgeting for a performance-built trans. Rodney at RPM (forum sponsor) has a great reputation.

Torque Management (also referred to as abuse limiter) is designed to keep you from smoking a stock A4. It controls the torque output of the engine to be a bit more gentle with the transmission. On my A4 car, I installed the DiabloSport Predator (handheld tuner), and it dialed the TqM back a lot - the car became rather more snappy.

Some weird stuff going down.my '98 2.73 coupe will spin them at will, no questions asked.. my Dad's 2000 2.73 was reluctant to do anything resembling wheel spin in a strait line.. of course 500+rwhp seems to have fixed his issue.

Maybe you just have very sticky tires? 
Also, if its cold out Z rated tires spin real easy and the engine makes a little more power. If its a hot summer day then that's a different story...

I have 3:15 rear and it will easily spin the tires if I hold the brake for a second, but they don't squeal. Maybe that noise you hear is the tire spinning on the road. Have someone watch for you.
