Hello. Anyone run 3.91 gears in 2015-2017 mustang gt automatic? I bracket race at Milan Dragway in the summer on the weekends. I've got most major bolt ons with some suspension upgrades and 3.55 gears with stock cam and converter. I run around 12.3 in good weather. In my class, 12.0 is the limit for 1.4 mile. I'm looking to get to around 12.0 or 12.1 and wondered if anyone has run 3.91 or possibly 4.09 gears in their automatic.
Thanks,
J.D
