i have a little problem after i did a stage 1 ecu remap
my mpg has decreased significantly
when driving in town i can see the km range drop every 5 - 10 seconds by 1 km
example whan i start up the car i have 250km left on fuel and after mayby 5km of driving it dropped to 210,while driving very normal
when driving on the highway and using cruise control it comsumes fuel normally (or even better?)
does anyone knows what the problem is?
its a bmw 520d - year 2010- manual - 163hp version
i have asked the tuner to just push the engine to it's limits without dangering the car components
i did not ask him anything about fuel efficiency
could it be that he remapped the engine so i have non stop torque at the low rpm's (like 0 - 2000 rpm)
if so, would lowering the torque from 0 - 2000 rpm will get me a better fuel efficiency?
i have added a picture, these are the results of the remap
thank you in advance
