Just bought a 525d se, is it worth remapping? I had a a3 tdi sport remapped that to 200bhp and it still returned 53mpg any ideas on what my beemer would do and what problems would likely to occure if I did do it?

 

I have just remapped mine and OMG it makes it feel like I am driving a different car. my car is quicker than my friends standard 530d now

I used ecuremapz.co.uk based in High Wycombe
