Hi, i have a 318d saloon with 2.0 116hp m47 engine (2004/6), and i see all these remap sites on web saying that the 318d could be remapped to 144hp, at other forums they say that the car is basically a factory detuned 320d and the 320d can be mapped to 180hp. What is the differences of the 2 (physically same?) engines? How come the same engine cant do 180 hp?

Okay found it out by google:

ECU mapping
Uprated fuel injectors on 320d
Uprated manual gearbox on 320d, with higher torque capacity and longer ratios
312x24mm front brake discs on 320d (as opposed to 300x24mm on 318d)

fair enough.
