Should I cancel the EGR?

Plus, the performance will increase slightly, but the minus failure light is on.

I have 3004-307-hdi-1.4-68hp-xr, egr cancellation did not make much difference, obviously, there is no noticeable change. I did not mention the valve, maybe there could not be any performance increase in that percentage

I asked this question too, but I couldn't find an answer. As far as I have heard, I do not know how real the burnt gas is not given to the engine as it prolongs the life of the engine.
