Edit: now I’m totally confused according to some other threads here the ZL1 does NOT have AFM valves.....

Correct. The LT4 engine in the ZL1 does not have AFM. The LT1 engine has AFM hardware but it is isn’t active on M6 cars. The M6 cars don’t have AFM valves in the exhaust.
Track Mode opens the NPP exhaust valves initially and under acceleration but I believe even in Track Mode the NPP valves eventually close with steady driving (i.e. highway driving). The M2W controller gives you the ability to override that.
