My first time at the track ever (as a driver) I was running between 12.86 and 13.18
now given I was locked outta 3rd gear (yes the '13 still has that issue not sure on the 14's) and I ran with full tank of gas (wasn't expecting to run that night).
The Track was Castrol Raceway in Leduc, Alberta, Canada which sits approx 2300-2400ft above sea level.
I have a '13 GT
Stock 245/45/19 Pirelli's
Steeda 101mm Intake
JBA Xpipe /w Cat Deletes
Roush Axle Back
Bama 93 Race Tune
2 issues with 11-13 mustangs
1) locking out of gears (heard mainly 3rd)
2) clutch pedal sticking when shifting at high RPMS
I resolved my issues by putting in a Barton 2 post short shifter and removed the helper spring and none of those 2 problems has come back yet.
Some have said they had to change their clutch line to resolve an issue but I thankfully didn't have to go that far to resolve mine.
Manual trans all the way
I would love an auto for rush hour traffic but I thankfully don't drive much in rush hour traffic
