I believe that you can change a couple of thing on the motor in order to get better fuel con what can I do I can only getting around 8km to the liter and just make 500 km to the tank
That's typical for one of these vehicles and some people are doing worse. Good luck doing better than 10 km to the litre.
A heavy vehicle (1500 +kgs) and 2.5 litre Turbo is not a recipe for terrific economy. The engine is always going to be working hard.
Aside from how you drive the BT50 the best way of achieving good economy is regular servicing of the vehicle. I would not recommend allowing a tuner mess with the engine's computer settings.
What some are doing is fitting much larger wheels and tyres thus changing the gearing in the vehicle. However the speedo will need to be recalibrated if you do this to make the speedo and the vehicle legal/roadworthy. This will give you more economy but you are increasing unsprung weight and your acceleration will obviously be reduced in a higher geared BT50 compared with the standard spec. There are also legal limits in some juristictions on how larger you can go up on tyre size beyond the largest tyre fitted by the manufacturer on the model of vehicle.
