Powerbox and insurance

Hi, thinking about getting a Powerbox for my Twizy, should I inform my insurance company that I have ‘chipped’ my car?

The official answer should always be yes, however in my experience “chips” etc are always a confusion point to insurance companies.
I have always declared mine in the past as they have been by known tuners so has been abit easier, I suggest you speak to your insurance company ahead of a purchase and ask what the change in premium would be if you purchased. Then you get an idea of their competence in this area, and what the cost will be.

Unofficially, with removable and switchable maps many do not disclose.
