A few insurance company's so far have asked me the modified bhp against the stock bhp. I've been saying 180 bhp in stock form and obviously 215 bhp after the mod to which they say ooooh that's a big percentage increase. I'm just wondering if the 180 stock figure is technically right due to this over boost thingy going on which I don't understand. I want to be legit so what exactly are the figures I should be saying?
