So me an my buddy installed some 4.10's on his new edge mustang. The car drives fine with no noises but it feels the same ...after all the talk about 4.10's being the **** we are very disappointed , he thinks he should have gone with higher gears..The car has not been tuned yet but I can't see how the tune will wake up the gears. His car had the stock 3.27 gears before.
