a friend of mine told me that even you de-fap your car you need (psa-citroen) to deactivate the eolys system using lexia.
is lexia able to disable this system? or should I use a more technical software?

plus, I saw on other forum a guy removing some unused valves involved in the fap and egr system
Is it really necessary to do this?

the translation (I know the names in spanish) of the valves is

"dpf regeneration commander valve"
"intake butterfly valve"
"egr valve"
