I don't believe the 4.7 either but it's fun to see it. The truck is fast tho. It's noticeably faster than the 4WD Tundra I test drove.

Another GPS data point: I use Track Addict app at the track for lap times and for one session I also ran a borrowed GPS lap timer. The app lap times were with a few thousandths of a second to a few hundredths of a second compared to the $400 lap timer. I doubt the G force readings and actual GPS position of the app are any where close to as accurate as the real lap timer but at least the lap times are accurate.
