exhaust parameters can't find...

A total noobie question here. I purchased (4) credits for my 2023 ZL1, can't find the exhaust group in navigator. I did the online "Tuners Tools" and went through the for parameter access codes, linked device etc. But still nothing, so I bought 2 additional credits, synced device, it showed a quick message that it was adding (2) but after that and then checking my licenses count, it still only shows 4 total. So I'm totally missing the boat here I'm sure. Any help would greatly be appreciated. Thanks

Exhaust stuff was removed for epa bs and yes even though you took the class doesn't mean you're getting access to it. As for the credits, I recommend contacting support.

Yep !!! They few that want to change this will cause Global Warming I'm sure !!! Not like the masses that do so much more ! I will live with what I have ! Thanks EPA !

So, one thing I did find once I licensed my CCM. Was all the exhaust parameters I wanted to change I could! In fact, for my 6th gen ZL1 it has a parameter for "Exhaust Rumble Enable". I set this to '0' for Performance Mode 0 (for me that's Touring mode). This did exactly what I wanted, the car now starts up quietly, just like Snow / Ice mode. But for my default start-up mode Touring. That prevents me from needing to press and hold the start button for 10 seconds to get the car in run mode where I can change the performance mode to S/I to get a quiet start up! So that was a good deal!

Can you post the tune with the ccm?

I haven't had HPTuner in use since last fall. So the EPA eliminated access to CCM. Have they also limited/eliminated ability to update software as well? Haven't seen any updates in some time.
