Erg block and fuel consumption

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..

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.

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
