Thanks, Rob, and I certainly agree - you are there to have fun and to run fast with your installed system. It'll be a great opportunity to try a number of its different settings, so I wouldn't worry about trying to fit in the stock runs. Maybe another time somebody with an 'off-the-shelf' 28i can join you for a night at the races. It might help to see what the 28i's baseline really is on that track so you can each compare your different tunes and their actual effects.
