My car came with 3.25s, and with the 235/60/14 tires, it seemed to tach out about as much as it does with the current 3.70s and 275/60/15 tires. I will likely keep the 3.25 third around in case I decide to take a long trip with the car. The 3.70s are okay for quick freeway jaunts, but it is revving above 3,000 at freeway speed (60ish).
