Does anyone put the lockers in?

 

This is my brothers slip from last weekend, 75° outside
2013 fx4 screw 3.55 locker, he made 11 passes in 4 hours and this was his best, he tried a boosted launch with the locker locked in 2x4 but no luck, had to use 4x4 every time.

He was running the 93 octane livernois tune.

 

I know this is an old post, but a 2.1 60ft feels like a rocket ship being towed by a toyota...


a 1.3 or 1.4 60ft on the other hand is something to be proud of

 

They have the ecoboost f150 crew cab 4x4s running 13.4-13.5 with 93 octane tune only !!!

I don't have my slip handy, but my stock SuperCrew FX2 EB pulled a 14.5 at 57°, 17mph headwind, 3rd run.
