Yours is slightly better than mine £40 approx gets me 150 miles!! You get some serious MPG, your Glanza got 100 miles to a tenner? How the fuck? NA Starlets only do about 70 miles max to £10. Do you travel long journeys? All my miles are local, I've been told that wastes a lot more fuel. It's a TD04 @ 1 bar on an Apexi Power FC. It is overfuelling in the low revs, but I didn't think it could make such a difference to be honest. I will get it remapped though.
