I went from the 2.73 to the 3.31. Highway mileage went from 31-32 down to 28-29. City driving saw an increase from around 19 to 21-22. ....and the pedal is pleasantly more responsive. IMHO the sound of the 3.55 and 3.73 RPMs would get tedious especially since I do alot of highway driving. With the 2.73's I could hear the engine lug on highway inclines. The 3.31's fixed that!
The RPMs for the 4 gear ratios at 70 mph are approx 1700, 2100, 2210, 2320.
