example a 2003 PT Cruiser Turbo auto has a 3.91 gears,because the car is 3500lbs and the 4 cyl does not have much power so they went up in gearing.

A CAI, and a propper gear is all the NA Crossfire ever needed to be competitive.
For the SRT's....it's just down right AWESOM!!

I recall looking at some Dasdaq data and the 3>4 change was just before the 1/4 finished = another gear change.
At the time I questioned - given the ammount of torque we have for the weight - would it be better to go with a shorter diff....say 2.85-2.9
and if your target is 1/4 mile - 2 gear changes instead of 3.

Hopefully I can leave it alone and never have to make a choice.
