Does anyone know how to state an STI PPP for insurance purposes?

I know its roughly 15% power increase, but is that say 10% chip and 5% exhaust, they seem to want to know exactly.

 

Most creditable insurance companies know what PPP is mate..... if yours doesnt i would go find one that does .... ie liverpool victoria or norwich union

 

Unfortunately Im 28, so dont think liv and vic will touch me. To be honest I havent found any that have heard of PPP so far, I didnt think Norwich Union were that cheap. Basically a standard STI is about £800 for me and PPP tends to be about £1300/1400 ish which I think is a hell of a jump !
