Blanked of the EGR valves today, which I've been meaning to get around to doing for a couple of weeks. Result is a far more responsive car, quicker off the mark and just more driveable. The turbo spools up faster (only natural it would of course), so all in all very happy with my transformed 2.7, which are underpowered to start with so it all helps. Time will tell regarding the fuel consumption results. Next step - remap
