coreying: woah, the DSG makes more of a difference than I was expecting! I assume that's with launch control (which my 118TSI doesn't have)?
I haven't ever tried simultaneous throttle+brake on my Golf, except for a couple of times when I accidentally forgot it wasn't a manual and floored the brake expecting it to be a clutch pedal and simultaneously put it into neutral instinctively trying to change gears ... oops.
