Just posted this in another thread but could be relevant here too.
Ive just done a fuel test, UK gallons.
63 Litres gave 398 miles = 28.72 miles per gallon = 10.16 Kilometres per Litre.
http://www.geocities.com/mpgcalc/This aint bad for 1995 2.8tdi (Frontera) with suspension mods.
The particulate filter and cold start flap has been removed from the exhaust and the EGR valves have been removed along with most of the pipe work also the pipe from turbo to EGR valves.
Ive also removed the cold start flap on the air inlet between the intercooler and inlet manifold.
This has noticeably increased the lower rev range and it pulls a lot better down there.
Im not sure which made the most difference as they where all done over a day, but it has transformed the drive.
113bhp stock.
It made that much of a difference I was considering upping the fuelling but Im happy as it is and I will not be fettling with the fuel pump no, thus saves a few miles in fuel lol
