There are a lot of variables, do the testers adjust tire pressure? When I bought my 97 Supra turbo 6-speed I was able to get 13.4's on the OEM tires which beat out the 13.5's that were published. However, what helped is the fact that I lowered the tire pressure so I had a larger foot print. Same goes for the 6-speed, if you slip the clutch out (this works on any rear drive car) you will load the rear susprension and the car will launch better. The 7-AT is more consistent and will also benefit from loading the rear suspension a little as well...I've had my car in cool weather spin 1st through 3rd as I'm sure everyone else's car has done this as well yet, loading up the suspension makes a world of difference which are reflected in times.
Each review I've seen the tires sit and spin which tells me that is precious time being given up. I'm sure they follow a basic procedure however, with a little practice the magazine times can easily be beaten.
