For actual track days I usually use PTM 3, especially if I'm not familiar with the track. once I get more familiar I'll play with 4. The PTM on the track in 3 or 4 is very cool, it will regulate just the right amount of power to make sure you have maximum traction in turns. Here's one of my videos from a track day and you can hear in some turns the exhaust kicking in and out (for example 0:17-0:20) that is the ECU feathering power to maximize grip through the turns.
I pretty much do the same as Baylor....
