Erg block and fuel consumption

[BigRAWesty]

If you block it with stock exhaust you should have no issues..
Not sure with the 2 3/4 system though..
But yes around town you will notice a bit more fuel used.
As Hodge said you have more exhaust gas going threw so boost is stronger earlier thus more fuel..

When I blocked my EGR on a 2009 CRD, fuel consumption went up. The way I was explained is, egr blocked = bit more boost = more fuel per boost ratio = more fuel burnt.
Take that with a grain of pepper if you wish, but that's the way I understood it. Good tune up with needle and dawes after that and she was better then ever and fuel economy was great.

This ^^^^^^

Hey Hodge, sounds like you understand the principle more than you let on.

I was going to break down the statement but I really can't be fagged anymore. I will just leave it as my opinion, its way wrong.

After battery disconnected Done a few tanks on it now and cruising at 115kph long distance it sits at 11.4l/100km even got down to 10.8l/100km but overall with my short distances to work 9km ,of which most it hwy driving and so early morning I can't even get into overdrive as she's to cold nearly reach operating temp and I get to work .. But when I fuel up it works out at low 13l/100 so can't complain really and it defiantly drives better
