Hello to you all from the land of expensive fuel. As the distance to the Russian border (and cheap fuel) I decided to do something for the fuel economy instead.
Car: 2003 Citroen C5 Break, 2.2HDi + 4spd auto
Current mods: tuned ECU, low rolling resistance tires, FAP deleted, EGR blocked, some car weight deleted and adjusted driving style. Doing now 5.3l/100km on mostly highway cruising (~44 mpg).
Interested in aerodynamical mods. Too bad replacing the auto with stick tranny is a job far beyond profitability. These computer cars need half of the stuff replaced inside when you change the transmission...
