Just because you load the engine more in 1st gear does not necessarily mean the car will go any faster. It still comes down to moving X weight over X distance with X power. The gear you pick just makes your car more or less efficient over a certain distance.
As a general rule of thumb, any high power car is easier to drive with a taller gear like a 3.27 or 3.55. It's less shifting. If you don't mind shifting a lot, a 4.10 or deeper gear will almost always give more performance. I guess that also assumes power shifting on a manual trans. If you're a granny shifter, then you'll want a taller gear.
We did several experiments between auto and manual transmissions, and different rear end gears, and it still took the engine the same amount of time to spool all the way up to full boost from idle at WOT when compared to dyno numbers. It was very interesting to say the least.
