Hi, do these make a differance? I have blanked off the ERG in th Disco, tweaked the fuelling and fitted a decent filter but she still is a bit sluggish compared to my 300 90 with the same done ( only differance is the 90 has no cat) so is this the cure to remove it in favour of the straight though jobbie??? cheers all....
