Remapping a 330Ci

[car.chic]

I'm currentely considering whether or not to remap my 330Ci, is it worth it?

Also would i need to declare it to my insurers and would they charge much more?

So for big gains supercharging seems to be the way!!

Would it be as quick as an M3 supercharged?

To who's had it done, have you had any problems?
