Robert21 Member 15 Member For: 10y 6m 5d Posted 09/05/14 12:45 PM Share Posted 09/05/14 12:45 PM Hey guysI've had my manual '09 FG XR6T for about a month now and I have noticed that my avg fuel economy is really bad.it has 90K on the clock and I'm averaging 16.8L/100This is easy city driving and rarely going over 2.5k rpmI was wondering what mods I could do to drop that number because im only getting about 350km from a full tankCheers guys Link to comment Share on other sites More sharing options...

Also a tune on the boost controller, program it to stay open& seek less boost lower down in RPM/Vol efficiency map Link to comment Share on other sites More sharing options...

A cooler may also help but I would put that down on your list of "economy" mods And just remember anything exhaust wise will need a tune Link to comment Share on other sites More sharing options...

Even my last falcon (not a turbo) was the same. When I was doing short trips I found even if I babied it I saved f*ck all so just enjoy it and forget about the economy! 2 Link to comment Share on other sites More sharing options...
