HP loss? I just bought a '98 T/A no WS6, automatic with 70K on it. After the purchase i took it back to my mechanic (who had inspected prior to the purchase) for some tune-up stuff. After talking with him, he seems to think that the car is underpowered for some reason. He says that there has been an identical T/A in his shop and it gets up and goes a lot faster. I can't burn the tires at all in this car, and i don't know whether its traction control or if the stock HP was not sufficient to lay down some rubber. Any thoughts? All ideas are greatly appreciated because i'm stumped. No trouble codes, nothign mechanically wrong. My mechanic thinks its a tuning issue.

Does it have bigger wheels on it? Cause when i put my 18"s on my bird it wasnt as easy to burn them up as it was with the stock 16"s. But once i put my lid and cat-back on i have no problem now. Also bigger wheels slows things down a little bit on the top end.

Hmmm... my Formula will roast the tires no prob, even burn out and fish tail if I floor it at 10mph roll. What kind of gas do you have in there, I once put 89 octane and the car was slow as HELL, and I mean slower than a honda civic slow! I put 93 in again and it was fine again. That will make a BIG difference.
If you already have 93 octane in there try putting some fuel injector cleaner in the gas maybe. You might have bad/clogged fuel injectors.

I doubt there is anything wrong with your car at all.

I bought my 98 A4 T/A this year with 74K miles on it and i have had absolutely no problem doing burnouts and all kinds of 180's and 360's in it. i know i have the factory 3.23's in it so i don't know if that makes a big difference or not but i haven't had a problem at all with power and i am bone stock at the moment.

As far as gas - i always run 93 octane. My tires and rims are stock. Would traction control actually stop the car from spinning the tires in first gear? If so - how can i disable it to find out?
Any help is appreciated. I as a little dissapointed in the low end performance w/ LS1. My previous vehicle was a '95 that i swapped an L67 (s/c 3.8) in to and that car would have killed my T/A off the line. I am looking for some solutions for my acceleration woes!

Just took a crash course in f-body rear ends. I've come to the conclusion that i do indeed have the dreaded 2.73 ratio. Would you reccomend doing the rear end or the torque converter first? Or should i do them together? Should i get 3.23 or 3.73? What stall converter? I'm really just looking to get up and go quicker in my T/A. The only modifications i plan on doing are a k&N intake and the t/b coolant reroute. This engine is plenty powerful enough for my daily driver, i just want a little more kick!
Thanks guys, i appreciate the community support here.

I had 2.73's in my 'bird, and I later switched to 3.73's. I wouldn't bother going from 2.73 to 3.23 (or 3.42's for that matter).
There are several f-bodies on this site that are running super-quick times with 2.73's.
As far as leaving the motor alone, all I can say is good luck with that.....you'll get the bug and won't be able to stop modding.

I personally would not do 3.73 if you are using it as a dialy driver and have gas milage as a concern. With gas prices not dropping anymore than they have and maybe going up again next year I would not go that far on my daily car.
I have a 01 LS1/M6 car with 3.42 and I think they are a perfect blend of performance and cruising speed.
I dotn know if you can swap right over from a 2 series carrier to a 3 series carrier without getting a new carrier as well.

3.42, 3.73 & 4.10 = 3 series carrier
I bought a really nice used 3 series carrier on ebay when I did my swap.

Soory, I'm not used to rear-wheel drive vehicles. Whats a carrier? Are there any other parts i would need to get to have a shop install a 3:73 gear ratio posi? Any insight on the T/C?
a TC (torque converter) will make a big difference in the performance off the line. then with a set of 3.73's in there, the car will have major traction issues. Ive heard that TA's with 3.73 gears @ 70mph are only at like 2800 rpm or somewhere around there.
