Bros, as said earlier, the remap will cost about 2500-3500 depending on requirements. As my personal experience, my remapped 118i goes like a bomb n could give a golf GTI a run for its money even though it is a NA engine (tried before). If the throttle is slammed hard, it goes to 6000-6200 rpm easily before each gear change on auto. It must also be noted that after the remap, my car runs on RON 95 smoothly n gives me better fuel economy albeit more torque & HP. I suppose there are some shops doing remaps but getting one who does it with dedication & passion is a totally different ball game. This guy who did my car is passionate doing it, I know as I spent several days with him getting my car tuned to my requirements. In fact, I am in discussion with him to collaborate with me to set up a remapping shop in JB to cater for enthusiasts like me. If u guys in KL are willing to get yours done, I can try to set up an appointment for him to go to KL to get your cars done. I just got a new X1 and am contemplating very hard to get it remapped too, or wait for me to set up shop then do it.
