    Can HPTuners disable codes for catless?

    I know there have been crackdowns on tuning companies in this in the US.

    I just want to make sure it's definitely possible to disable catless codes as a result of using long tube headers (replacing primary cats) on the M156?

    Thanks in advance!

    You can switch sensors on or off for diagnostic purposes, yes.
