i dont recommend the gear swap to 2.73. ive recently gotten into an '02 vic and i feel like the 2.73 set leaves a lot to be desired unless youre doing 70mph, not alot of torque available in OD. if youre getting near 30mpg with 3.55 id say youve got the right gears already. in comparison my dads mustang gets 30mpg with a 300hp 3V 4.6, a manual trans, and 3.55:1 gears.
