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.

 

Please tell me how the difference feels!!! Thanks!!!

 

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.

 

Duuude...Awesome!!!!

 

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
