I was looking into how much it would cost to insure a chipped car and my insurance compamy will only quote to a 25% increase in power.
Do they calculate it from the standard ie. 150 - 187.5 (+25%) or do they calculate it from what the car actually was developing when on a rolling road?
I would appreciate any information on this.
It's only a guide, they're not going to penalise you for being a few BHP over. The 25% rule will cover mass market stage one remaps. Anything more than this and you will have to get specialist insurance.
