Help. Engine trouble

I have a 2012 JKU Arctic. Jut put Rock Krawler 2.5 inch lift, 35's and got a Superchip Trail Dash. While driving around town 45mph or less no issue. When i get on the highway and get to speeds of 60+ mph i get a check engine code of P0390, P0394, and P2638. Electronic stability control (ESC) light will come in also and limit me to 20% Throttle.

Has anyone seen or heard about this?

Did you center the steering after installing lift? Also input the correct information to correct the odometer?
