First Tweecer datalog, where to start?

I almost died of old age deciding which tuner to go with. Decided on a Tweecer RT from Chris at Poweradder Solutions. He's given me awesome customer service setting up my base tune. Don't want to call him until I can hold up my end of an intelligent conversation. Ready to do my first datalog. New 306 has a good 20 minutes on it and hasn't left the garage. (mods in signature) Sounds really good to 3000rpms (haven;t had it higher yet). Idle sounds nice at 800rpm, right up until it suddenly dies and seems a tad flooded when I try to restart after stall.

Anyway, what should I datalog first as I begin my ascent of the learning curve of Mount Tweecer.
