just fitted the egr delete. just a quick question. you know the 2 vacuum pipes on the egr. i've put a screw in the one that was connected at the top because thats what i read somewhere. but what do i do with the other one that comes off the egr actuator and goes to the switch bolted to the inlet manifold? i've done the same and put a screw in it but not sure if thats what i'm supposed to do.
