Is my car under powered?
Its been about 10yrs since ive owned an fbod, and never an a4 ls1. All have been 01/02 m6. This one i have know is a 00 a4 and i just did headers/oryp/lid/egr-air delete. A few days ago i went WOT from a dead stop and it didnt even break the tires loose...295/38/18 potenzas. I was expecting more, or maybe cause the others were manuals but i remember it was hard to keep in in a straight line.

Was traction control off?

Yeah I thought about the gears too, I got 3.23 right now. But also did WOT on a slight roll and was expecting something from the transmission dropping gears, like slight head being pushed back....but nope. I don't drive it much and a few weeks ago when I did the same thing it bogged on me. Didn't WOT until this time and got these results.

No it has not been tuned yet. Interesting u mentioned the MAF though. About a year ago it was kind of doing the same thing, threw codes about both banks being lean. Friend told me to check the MAF. It was covered in linth and crap, probably could make a teddy bear lol. Cleaned it and it was running great, perfect...great power. Maybe has something to do with that again. Good call.

I know the OP has already mentioned having 3.23s, but this wouldn't matter either way. Both of my 2.73 LS1 cars had no issues burning street tires from a stop even when stock and with fresh rubber. The 3.06:1 internal 1st gear of a 4L60E gives even a 2.73 car a better launch than one might expect from an old TH350/400 or 200/200-4R with similar rear gears.
An MAF cleaning and fuel pressure test are both great advice. Also, I'd get it tuned for the header swap before evaluating any performance concerns (but, of course, you'll want to make sure fuel pressure and MAF operation are proper before getting it tuned).

What makes you certain you have 3.23's? Does your RPO sticker show GU5? In contrast to RPM and 99 Blackbird, my car with 2.73's and very low miles wouldn't break the tires loose from a stop. There may be another problem but your description sure sounds like the way my car was with 2.73's.

the only time i could not break the tires loose with my A4 2.73's was after engine work i was throwing a code due to a teeny tiny wire off the back of the intake to the computer was broken. the car had about as much power as my nissan 4 popper.
