Wow I didn’t know that. So when in “Sport or Track” modes what differentiates what each valve will do? And is there any pictures you could share on where the AFM valves are? I don’t remember seeing them under the car when I was installing my borla exhaust this past weekend.
Edit: now I’m totally confused according to some other threads here the ZL1 does NOT have AFM valves.....
