Am looking for some advice regarding remapping my car bmw x3 3.0sd msport. I have seen a lot about other models being remapped but not mine. I would like to know if anyone has remap this model and what are the benefits. Also am more intersted in economy wise. I do a lot of short run and recently seen a fall of MPG,getting about 28-29 MPG at present.
Any advice is highly appreciated.
