trac off for burnout, track on for pass (never engaged on the 13.0 pass), in drive (autostick was slower et's). we got about 25 passes in that day trying different combinations, found 32 psi to be the sweet spot for the rear tires, anything lower then that would hurt the trap speeds and did not help the et's.

the passes when the TC did engage my ET's were 1/2 sec slower.
