I recently had 2 2019 GTs built for track use only, but now the auto rev match on downshift does not work in either car.. Both cars had AC and stereos removed, along with a bunch of other stuff. No codes are being thrown. both cars have custom tunes.
Any ideas? BCM maybe? I don't know shiznit about these cars..
