Guys, I was very happy with the consumption of 206 hdi min. Until a few months ago, there were wheels and exhaust in the car, of course, a little bit of consumption. now I have turned it back to its original state but my consumption has not decreased, it is a warehouse that takes around 750 km from the city, it used to be 850 departures. Car 2003 model. Does the engine have to be connected to the computer at the authorized service and the necessary adjustments (injector settings or something) need to be made? or throw new software or something into the engine? What would they cost? Does it find the chip tuning cost?
