I've only made five passes at the strip with this build, and all were in Sport with TC off. I'll try Track PTM mode next time. This morning's cruise was also with TC off in Track mode. I didn't use PTM.

Of the posts I've read the informal consensus seems to be Sport for drags. I'm less sure about what track guys have said except I believe the author of the post I referred to with the table that shows all modes/settings said the ZL1 is faster in Track with all nannies off. I'm betting nannies were off on the Nürburgring ZL1's runs.

On a road course in a ZLE, Track mode and PTM Race is the fastest WITH the "nannies" still engaged--which is wise for 99%+ of drivers.

The true fastest mode for a GREAT driver on track, like my old coach who set some lap records on tracks, is ALL stability control including PTM FULL OFF. But you better be a truly great driver to handle that or you will crash your ZL1.

I don't recall which model the ZLE driven by Bill Wise was in when it set that fast lap on the Nurburgring. I'm guessing all stability control FULL off, and that takes balls on the Ring at those speeds--the guardrails and deadly trees are so damn close.
