Not a performance upgrade obviously but enables a person to get at stuff a little easier with the coolers removed.
Exactly, I will also add this…..When running tunes that do not cycle the EGR valve, soot builds up and when & if you have to go back to stock, your EGR valve will not work. If you do not have to worry about emissions, I say ditch the EGR coolers and valve entirely.
