17L/100kms with RB25 - solution?

[rb25]

to add to the thread, i recently put a powerfc in and am getting really good fuel economy. best on the highway was 11L/100km and worst was 20L/100km, lots of WOT. The car makes 170kw atm (rb25 of course).

yeah i might just live with 13L/100kms for city driving...might see if the r33 service manual has ways to check other things like EGR, but it seems 13 isnt too bad. hopefully i can get highway driving under 10.

im thinking of getting a pfc later on down the track, once ive paid fof remaining $600 on the car, and got some new tyres...but 11-20L highway isnt that good is it?
