Here are a couple launches I did. The first was when I was still stock and still learning how to use LC. I held the rpm's at 3k and pretty much spun my tires for all of first gear. The second video is with stage 2 and I learned the sweet spot for launching is around 2100 rpm's. The tires hook up well, but the DSG effed me and shifted into second a bit too soon. I've launched perfectly a few times, but unfortunately it wasn't being filmed. :/
Pretty awesome.
I used it for the first time today. I'm completely stock, so I think I can rev a little higher. I was at 2,400 and didn't get much tire spin.
