The gears alone made the car feel a lot better before I had it tuned with the programmer I bought from American Muscle. I highly reccomend them, I chose the 3.73's over 4.10's because I didnt want to have to shift every 2 seconds, and I didnt want to kill my highway mileage. At 65mph the car is right at 2000 rpms and the car gets 20mpg mixed city and highway speeds of 35-65mph, and 23mpg on the highway at 70-75mph... Just depends if you drive a lot on the highway and what your goals are for it.

I'm debating between 3.73s and 4.10s for my 04 GT auto... I know they say 4.10 auto but I have crappy 245 tires...

did it make a huge differnce have an 01 gt with same mods except flowmaster have 93 sct tune except i have straight pipes trying decide with 3.73 or 4.10

so you really feel a big diference with the 3.73 gears dude? i mean, the car gets faster than with the stock gears? cuz im thinking about the 3.73 or 4.10

have you ran it at the track since you installed the gears? i wanna know about how much 1/4 time ill pick up with a gear swap

lol mine aint shit compared to 3.27's i have 2.73 economy gears not great for launching
