Curovo, I appreciate your clear descriptions of your "lag", and I've tried mightily to duplicate it...full throttle launch from a standstill...
I have a confession to make. I am (almost) incapable of mashing the pedal to the floor. At age 56, I've just had too many thousands of miles under my belt to "abuse" (yeah, I know...I'm a wuss) any vehicle with an instantaneous full depression of the throttle.
That said, I tried it today...a few times. You're correct...there is more lag with this type of throttle input, very little forward movement, and RPMs do in fact rise to 2k before there's any real action. It was a bit scary, in fact, but no traffic around.
Then, I tried my "learned" version of driving with a DSG...rapid, but gentle, incremental fuel-feed, and guess what? Clutch seems fully engaged at about 1200-1400rpm, with a bit of controllable wheel-spin. The end result? This method will easily beat the "full-throttle" method off-the-line, and in fact, except for that split-second of clutch slip, is plenty fast.
I know I'm repeating what others have said in the several threads about DSG lag, but to try them back-to-back with full-throttle, the difference was amazing.
I tried this in my JSW, which had the mechatronic replaced (hard shifting) at 18k miles, now at 39k miles, with Revo chip (does EXACTLY as advertized...pulls to redline!) installed at about 25k miles. I'll try this same "test" later in my wife's stock sedan, with 24k miles.
Hope this helps clarify things.
