i was going to for one of my last runs but they shut down the track early so ill have to try it next time. i usualy pic up a tenth or so with them open for FATS times on 91 octane. i know they add a lot more with 104 octane and more boost.

i try to shift right before redline on all gears. so around 6900 or 7000.
