I have a 2021 with locked ECU that I want to tune. It looks like the JB4 is my best option but I want to know what others with either a Locked ECU or just don't want to flash tune are using. For now, I probably would Flash my ECU just for warranty reasons. I have a Function Werk catless down pipe with built-in defouler ordered that I want to install before any tuning but hope to order a piggyback soon.
So what Piggyback Tune are you using and how is it working for you?
