Been looking at better gear ratios for my 306 and this lead me to the final drive from a 206 HDi 2.0 Eco.

This got me thinking was the better MPG just down to the tailer final drive gearing or was there also a more ECO map on the ECU.


So looking of a dump from a 206 HDi 2.0 Eco (December 2000 - September 2003) (HDi badge has a GREEN i)
