the tune needs to be changed to the gears you installed.

Lol there in the right way and yesterday justin tuned my truck and set it for the gear swap. When I got home I turned the truck off and back on and the lights went away and hopefully they stay away

just do a search for ABS and you'll see several threads on the same problem. You'll just have to see when your is going off. (only at certain speeds?) and compare it to the others.

Likely the BCM needs flashed by a dealer.
