It was faster with the factory 245/70R17's. Now I'm running 275/55R20's

2WD. Short cab, short bed

No, I had the tune before getting the dragy. I'm using 93 ethanol free.

It drives normal till you go WOT

Rolled into 1st gear to avoid tire spin. Believe I can get a low 13 in the 1/4 with a better 60'

I got it the next day.

Mine is 2wd, reg cab with 3.31 gearing. 20" wheels with 275/55R20 tires . I love the power to weight ratio and the 10 speed transmission.
