How much was the labor? I understand you have to recalibrate the speedometer, too?

I was thinking of getting this:

So that the warranty on my 2011 GT 6MT wouldn't be voided, I guess having the work done at the dealership would be recommended?

Unless you really, really want to do it, I would suggest not making the change. The difference is not really that much.

I'm paying $350 labor for mine (SE Pennsylvania). Picking it up in a couple of hours.

The difference between 3.31 and 3.73 in "feel" is huge for me. 3.31 feels slow and lazy while 3.73 "feels" fast and lively. I am sure 0-60 is almost the same rather it's 3.31 or 3.73 but the feel is so much better in a 3.73 car.

Agreed.

Coming from 2.73 to 3.73 is like night and day (I own a V6 FYI). 6th gear is actually useful now. Every gear feels like there's a lot of power.

Best mod i've done so far.

the big difference might be at the end of the 1/4 mile when you lose a little time having to grab another gear instead of staying in 3rd<---- just guessing
