EGR ?

[NoTime]

What controls the opening and closing of the EGR valve? Is it several perimeters from several sensors? I’m just wondering if it would be possible to tune out the EGR? I know some older diesel pickup trucks EGR was mainly controlled be inlet air temp. I don’t mind the DPF or DEF stuff butt hate that my ISX has to run of its own exhaust.

Probably a stupid question but if there are guys that can tune a demandate why can’t we tune a EGR to stay closed without messing anything else up?

I want to demandate so bad but at the same time would like to stay legal without the high maintenance
