I would add that with the other basic mods I did like a Rotofab, removing the sound plate, and a Foster sound tube, I do get more whine in the cabin with my Soler. It's louder for sure than with the other mods alone.

Shout out to Soler Performance! TB works as advertised; gotta get the controller next!

Thanks

The stock throttle body size for the 2018 ZL1 is indeed 87mm. If you're looking to upgrade, the 91mm throttle body is a great choice for a stock vehicle.
Here are the part numbers for the recommended products:

91mm Throttle Body Upgrade (SE8223-080)
Throttle Controller (SE0525-TC)
This setup will work great for your weekend road course fun!
