Sometimes I have issues with my launch control. Just want to clear a few things up. So today I was driving with ASR off and dynamic mode on. I came to a stop, had the brake down, started to press the gas down fully and it felt like it tried to do a brakestand (didn't just rev up to 3000, it tried putting power down to the braked wheels).

So why is this? I know it launches without the gearshift being pushed to the right into manual mode, I've done it before. Do I need to perform the steps in order right before I'm about to do the launch? For example, come to a stop, then turn ASR off, then put in dynamic (sport) mode, then brake, then gas?

Should brake be pressed fully to the floor? Should gas peddle be pushed down slowly? I'm scared to just put the gas all the way down too quickly now that I've had this issue. Some input would be awesome.

Thanks!
