i say it would help with the gas because it would keep my in my powerband without having to have my foot on the pedal as much.
so its like this:
with the 2.73's to get the acceloration i want i would have to have the pedal 3/4's of the way in
with the 3.73's i would have to have the pedal 1/4 or the way in
so something to that affect
with the lower gears, i wouldnt have to use the accelorator as much since the gears would help a lot
