B8 S4 Launching

Hey everyone, my name is Chris and i am from greenwich, CT. I drive a 2013 S4 estoril blue. Some mods are PSS10 coilovers, awe exhaust, eurcode intake, laser interceptors, and probally a few more that I am forgetting.

So recently i sent a video to my friend who is a 335xi owner of me launching my car. He claims that you cant launch a b8 s4 because you will kill quattro, the transmission, and drivetrain. He says instead of dropping the clutch, you need to let it out slowly until it bites, but i feel this will just burn up your clutch. He says only dsg owners can launch their cars. However, doesnt dsg put the same amount of stress on your drivetrain?

Also, he is one that just flaunts his dyno reports, with his best numbers being 408whp and 480wtq on a mustang dyno. However, he doesnt have any 1/4 times lol. Auditude knows the full story with my friend Peter so hopefully he can chime in here. He also thinks that he will destroy pete in a race from a dig. Here is a video of my friend launching his 335xi lol.
