You already caught the fact that the 1LE has a 3.91 ring and pinion, but the 1LE also has a different version of the TR6060 transmission which has close ratio gears for 1st thru 4th. Combine that with rear tires which are both wider and stickier, and you have your answer.

On my last Camaro, going from 3.45 gears to 4.10s gave me 3 tenths by itself.
