2018 2500 6.4 exhaust and intake mods

[BigT9935]

i just installed a K and N cold air intake on my 6.4 and a flowmax xflow exhaust system. something just doesnt seem right. seems like having some troubles with shift point or goes into eco mode to much. do i need to do something to the computer. i know i changed the back pressure by eliminating the the stock muffler and resinator. if i do have to add a tuner which one is best.

Put the stock airbox back on,and see if it straightens out. Those 2 mods don't require tuning.
