A few more things - probably obvious:
1) Buy some 100 octane fuel. Drive at least 50 miles, including plenty of full-throttle to redline romps to give the engine computer time to adjust.
2) All electrical loads off
3) A/C off.
4) Remove EVERYTHING you can possibly remove from the car. eadrests, floor mats, the "mobility" kit (alone weighs several pounds), everything from the glovebox, door storage, excess fuel (an 1/8 of a tank will get you through quite a few runs) etc. Even the window washer fluid if you really care. I'll bet you can get 75 - 100lbs out without working too hard.
5) Wouldn't hurt to cool everything in the engine compartment as much as possible first too. Wrap ice packs around the air intakes and intake box - remove right before the race.
6) Sport mode on, DSC off.
7) Launch as described above. The goal is minimal wheel spin - when you launch from 1400, you can let the clutch out ALMOST instantly as you ALMOST instantly floor it. But you MUST make sure the clutch is fully engaged before anywhere near full power develops, because you don't want to fry your clutch. ABSOLUTELY don't slip the clutch in any upshifts either. Just BANG it. If anything slips, it should be the tires, not the clutch.
