I don't consider launch control a gimmick but it does take time to master the process. I've found the lower the RPM's the better (around 1200-1500). That said, I think that's why many have had success with just a foot on the brake - they are letting the supercharger fill up just enough before they mash the gas. My best 0-60 so far is 3.3 seconds and in Kansas we are experiencing high heat (88-93 degrees) and that was not using launch control. I'm confident those will be much better in the fall/winter.Sounds like most people are having issues with the launch control, so maybe there isn’t anything wrong with mine. It works as it should, which is just a gimmick at best. That’s too bad. My best time still shows 4.1, but I rarely go all out from 0-60, it’s too congested by me.
