Good tips. And I will definitely be getting the 4.10's after doing more research. By the way, I got a 13.1 second 1/4 mile time with my g-timer yesterday on the way home from work. And I don't even have 4.10's installed yet. Nothing wrong with this auto at all. 0-60 was 4.7 seconds. And I still have some room for improvement as far as the launch goes.
Do you plan on going to the track soon?? I would love to see the track et's before and after the gear. I do not think you will see 4/10th reduction from a gear change in the auto IMO. Good Luck and have fun.

I don't have access to a track near me. I'm in the process of taking some 1/4 mile runs with my G-Timer. I'll establish a good average and then after I install the gears I can see the improvement. Although the G-Timer is not 100% accurate, it will still give me an accurate improvement once I change the gears. And I'm definitely not expecting 4/10ths. I'll expect 2/10ths... and if I get more, even better.

Not sure why you say an auto is not the way to go. There have been plenty of great auto runs. I can do the research for you if you want and supply proof. Sounds like you spun the tires out a good bit, and may have some issues. But I don't see a problem with my auto, or autos in general. My car personally, which is an auto, does 0-60 in 4.7 seconds, 1/4 mile in 13.6 @ 102, 60' in 2 seconds flat. And I haven't even put my 4.10's in yet.

ok, i need some help, I went to the track here in Texas in my 05 auto GT and did 6 runs. first was a 14.4 and the next 5 were all 14.6's. Whats the deal?!?!?!?. All runs were done with overdrive off and TC off except one but it made no difference.The car is stock except for exhaust. give me some ideas, i have my time slips if you need some numbers. thanks alot

Yes, It would help for you to post your time slip. Which track were you at? Do you know the altitude? How many miles on the car?

There are lots of possible reasons so don't give up hope
