I agree - I blanked off my EGR valve on my 300tdi and it didn't help - it does stop crap getting into the intercooler though.
Turning the screw on the pump made a hell of a difference though. Far more power AND better economy. Some late autos had a chip though.
Having said that diesel and autos are a poor match. I had a TD5 auto that wopuld only do about 20mpg as well. It could be the price of fuel has fooled him into thinking the economy is down. A jouney that cost me £20 not long ago is now costing me £30 - good old government - only 72p tax per litre..........
