Does anyone know how the ECU compensates when the EGR VSV is opened? For instance, does it enrich the fuel mixture or advance the timing? Does it do anything? I definately want to remove this along with the charcoal canister but do not want any negative side effects. Again, not looking for HP gain, but both of these things are in the way and ugly...

Also, am I supposed to block the port coming out of the cylinder head when I remove the EGR? (the one in the pic)

I know some of the 5SFTE guys remove the EGR valve but is it possible to remove it from the N/A engine with no bad side effects? Would the ECU be ok or would a piggyback need to be added? Would there be any gains? Just curious

DON'T FORGET THAT THE EGR ALSO COOLS THE COMBUSTION CHAMBER BY ADDING INERT GAS. THIS REDUCES NOX AND IMPROVES FUEL ECONOMY
