Frank Gates again sets the standard with his first track day 2016. He runs a 12.49 @ 106.33 in his 2015 F150 EcoBoost.

Congrats to Frank Gates in his first outing in 2016 to run a worlds fastest to date 2015 F150 Ecoboost with SSi tune only. He still managed to pull off a 12.49 with a headwind of 16 mph and gusts up to 30 mph.  Where all the other racers hung it up and bailed out early due to the weather conditions Frank stuck with it. Congrats and great job Frank!
