Hey guys, i want to save more fuel for my FG xr6, want to do a few mods but still need to keep it p plate legal. I have put a xr8 induction with a k&n panel filter. Can anyone help me out with what i can do?

Average economy says 11.4 its was 12.8 before i put the induction on. It still seems to guzzle it down through to the injectors.
I have been looking around and there are pacemaker exhaust systems. so was thinking a full pacemaker exhaust with a tune obviously with a lsd?? Does anyone know how much kW this will gain. Probably to much?

Driving style is always a huge contributing factor in fuel consumption. A 4cyl car will guzzle if driven hard. I know my EF will hit 15-16l/100k with 'spirited' driving but I can get her down to 9.9l/100k by driving like a grandpa when need be, and that's out of a 350,000+k engine with very limited mods.

I am by no means criticizing your driving style, odds are you just aren't aware of a few different ways to lower consumption by changing a few habits.
This thread is worth a read and may help you improve your fuel consumption further. Hope it helps.

...well if you want to have economy, don't put the foot down. Putting an exhaust will probably increase the kilowatts and theoretically, economy will be better too...assuming you still drive like grandma on a Sunday. Chances are, the more killerwasps you have, the more you will put your foot down and the worse the economy.

11.4L/100km seems to be good for 50/50 metro/highway.

I do tend to give it now and then but barely. Im sure im not the only one. Ill take your comments in consideration. But i do want to add some mods aswell.

good flow (intake and exhaust) good spark (plugs, leads and coil) that's the best place to start.
