They often don't care if it changes power by less than 5%, lord knows how they expect you to know that, but typically an end can will never make that on its own.

Power Commanders seem to scare the crap out of insurers, in an insane way, if you got a quote for a CBR600 and a Fireblade the CBR would be cheaper to insure, declare a power commander and it would almost certainly exceed the Fireblade quote, so you get a @120BHP bike, fit something to get another @5BHP and the insurers charge more than if you bought the 180BHP machine.

I am assuming remaps would scare them too, although never declared one, and if you declare an exhaust system that adds more than 5% they charge you for all this extra power, and you need a map for the exhaust to work, but I bet they double fuck you for the exhaust and remap.....

...Try "go compare", you can put in the details of the bike in stock form, get the quotes, then try again with mods - but the more mods, the fewer insurers that will cover it, and that is often where the price hit comes from as the cheapest insurers tend to refuse anything more extreme than a tank pad.
