Default Actual performance gains from gear install?

OK, so I want to go to 3.73 gears in my 07 Auto GT. Right now I am totally stock. What kind of actual performance gain (0-60 and 1/4 mile) can I expect? Looking for hard data here.

Will the gains be magnified when I got to the axl back, CAI and tune in the near future?

Thanks!

What is your "stock" gear? Hard to say without knowing what you have now.

No (minimal)power gain from axle backs, just will SOUND faster.

DEFINATE gains from CAI & tune depending on what tune you get combined with other mods. CAI & 93 tune is advertised at maybe 20-35 HP, I think.

I believe the stock rear end in the Automatic 07 is 3.31 or something like that. I know that there isn't any gain for the exhaust, more just looking to see what kind of difference the gears will actually make. Has anyone done any before/after testing for 0-60 and/or 1/4 mile times?

Go 410 gears or you will regret it later.

4.10's are too much for an automatic...stick with the 3.73 if you have a manual...

Gains from these? There are all just seat of the pants improvement...It will pull harder and hit the powerband earlier...

As for 1/4...maybe .2? That would prolly be a stretch, but you will 100% guaranteed feel the difference...

I heard .2-.3 in the 1/4 mile and the car acts very differently FTW!

Only seat of the pants data but love my 3.73's in that department. I'd get the cai/tune first, your gonna need the tuner anyways to change the gear ratio.
