If I may ask, from where to where?
(Picking up 3 tenths with an 11 second car, and 3 tenths with a 15 second car are different things.)

That's in the 1/8. Car went 7.07 with the speedmaster's and 6.6x with trickflows. In the 1/4 the best it went with speedmaster's was 11.35, trickflows - 10.68, on the chip with the 1/4 passes.
