I'm new to the car, but shifting at 7k automatically just seems slower. I haven't done a ton of testing, so my butt Dyno could be totally wrong. Thoughts?

Completely relevant and, agreed, I've made the same observation. Compound that with the additional torque that your piggy provides you and I agree, better to short-shift (just a little). That said, launch control doesn't wring the gear out completely in my experience (certainly not in 1st and, I think, not in 2nd either) but, now that you've mentioned it, I'll take a look at the higher gears and see.
I posted launch instructions for my AMG E63S and in that car, the fastest possible 1/4 mile I could achieve involved using race start to get you going and then intervening with the paddles in order to shift slightly earlier than the race start programming would--perhaps the same is true here.
Thanks for the thought!
