Dear all,
I faced a problem with rev limiter tuning for 2018 Tahoe. I don't know if I can explain it clearly but I want that fuel cutoff sound when I rev up the engine. like this video ( https://www.youtube.com/watch?v=CqbMhGHiiA8 ). Find in the attached the calibrated file with no result.

Unfortunately we don't have too much flexibility with the rev limit strategy in the factory ECU so you're not going to have the required flexibility to change the limiter sound.
