[Adam2019]

Finally got all of my stuff installed.
2019 Laramie Sport 4x4 with Offroad Package and 25H (12” Uconnect, Panoramic sunroof, HK sound)
S&B Cold Air Intake
Flowmaster Super 44
ReadyLift SST 3.5”
Nitto Ridge Grapplers 33x12.50 (Using stock TPMS sensors from original tires)
Fuel Vapor 20x9 wheels in semi-matte black
Nfab Nerf Bars
Love how this thing drives but the gas mileage is pretty bad!

Any recommendations on the best handheld unit to recalibrate speedo and optimize performance? Something like a Superchips Flashpaq that uses ODB port....? Thanks!

Rough country makes a Speedo Calibrator

I was told by my dealer that the truck does it itself. I have the same truck as you but silver. This is coming from the parts manager that has been there for 25 years. He said it may take a couple weeks but it does it by itself. I thought that was neat. Said it was currently the only truck that does it as well.

Not sure this would be possible. The wheels and tire sizes are hard coded into the ecm. You can’t even change the tire pressure thresholds without a programming device. Not sure how the truck would know you have different wheel and tire sizes and auto calibrate the speedo.

All I can say is what he told me. I believe he said it works through the GPS. I’m 100% certain he said the truck does it automatically and that it takes a couple weeks and that at the time, probably a month or so ago, stated it was the only truck that did it.

We spoke about lifts and everything and maybe he is figuring once they do my lift, wheels & tires that they go into ECU and make an adjustment that allows it to recalibrate over the next couple weeks. Not that you just change wheels & tires yourself at any given time and it does it automatically. May. May not.
