Ryan Saleik Ford 2016 F150.hpt I opened up a tune file for a 2016 F150 XLT 5.0, and the tune file under the speedometer section says it has a rear axle ratio of 3.31:1. The VIN and the axle code on the sticker on the driver side door jamb says L6 which is a 3.73:1 gear ratio...
Truck has 114500 miles on it, and drives fine, kind of confused here.
