If you can do it safely on a private back road, try to get a 60-100 mph time split using the onboard timer. You should be in the mid 4s+/-. If you’re concerned about running to redline during break in short shift at 5500 rpm; it’ll add a little time to the split. Doing that a couple of times won’t hurt the engine. Try to get a couple of clean runs with quick shifting.

To get the 60-100 mph split, find a nice flat back private road. Try not to go with or against the wind if you can help it. Set the performance timer to measure 0-100. It will also measure 0-60. Take the 100 time and subtract the 60 time and you have your split. I’d start at about 40 mph in 2nd, then roll into it and be full throttle by 50 mph or so. You have to start the timer from a stop, but your split from 0-60 doesn’t matter; you just have to complete the 0-100 split within about 30 seconds or so. What matters is you are wide open before 60 and stay on it until 101. Again; make sure you’re way out on a back (private) road and it’s completely safe (no driveways, houses, etc.). M6 SS 1LEs should be in the 5s.
