doccrowley Posted December 10, 2012 Share Posted December 10, 2012 Just drove 400+ miles to Vegas in my wife's 2.5i. 23mpg's w cruise set @ 90. Mpg is more about your right foot than mods. Link to comment Share on other sites More sharing options...

bigjweb Posted December 11, 2012 Share Posted December 11, 2012 about 20-25 on 93 very easy on throttle, running 368hp 375tq HTA 68 ID1000 RACER-X FMIC JE Pistons Manley rods and a rack little crap not worth mentioning (need bigger turbo) I have a similar setup minus the ID's. I think those injectors make a huge difference overall. Link to comment Share on other sites More sharing options...
TRSCobra Posted December 11, 2012 Share Posted December 11, 2012 My old 334whp '05 5mt LGT bested 30-31 mpg on straight 65-70 mph highway trips. I attribute it to the TD06/20G-XT. Some times having a bigger turbo helps with fuel mileage because of the higher boost threshold. Link to comment Share on other sites More sharing options...
