On holidays at the moment - drove from Sydney to Brisbane in the VY and collected the following data, for those who might like to know.

Trip Computer Fuel Consumption: 11.0L/100km

* Wheels on car are aftermarket and may have a different rolling mass to standard.

That's pretty good for an untuned auto.

I'd be stoked if after exhaust + OTR + mafless the fuel consumption actually improved I'll probably do the drive again after those things and see.

I'd be stoked if after exhaust + OTR + mafless the fuel consumption actually improved .

Most likely they would, cause there the main reasons that restrict a cars power.

Recently my VZ Senator LS2auto mafless tuned (oztrack) on a return trip Sydney to Kempsey and back with 5 adults up and 4 adults back plus luggage netted 11.2L/100klm on the trip computer.
The computer was reset to zero when I filled up in Paddington, Sydney the night before we went and I filled up twice with the second/last fill at the same Paddo servo.
I was pretty happy with that considering the load .

Well done, thats pretty good. I know once we went on a trip in my old man's mates VY SS and got from Adelaide to Geelong on one tank...

I just drove from Adelaide right through to Melbourne on Tuesday and still had 1/8th of a tank left!! Which I thought was pretty good... although mine is the ecotec so a bit different obviously.
