Not sure if your question was answered, but it is a factory lockout feature that disables you from hitting the gas and brake at the same time. It's more for older folk that may accidentally press them at the same time and potentially run into a building. I have Ktuner on my car and I can confirm that Ktuner disables this feature so I can now brake boostHow many of you guy or gals have tried brake boosting, I’ve tried it it feels like the throttle just cuts out. Idk if I’m doing it wrong or what. Any tips ?
