This is only my second diesel car I've owned and I intend to have it at least 2yrs.

I'm interested in getting it remapped, if I do it will be for economy reasons and not for performance reasons.

Anyway, a few Q's;

Does everybody with a Diesel get them mapped?

Who do you recommend for the job?

How much should I expect to pay?

Is there any reason why I should not get it done?
