Hi, I've got a mk5 1.7cdti 100 astra, insurance renewaltime is rapidly creeping up on my, i've just bought atuning box for it, but don't currently have it on the car. whilst hunting online for quotes, when i add that my car is modded with a chip it asks for power increase from 0-10%, 11-25% or 26%+.... i'm not sure which category it would come under. i've just turned 21 and have had a 'not a fault' accident i have to declare so insurance isn't the cheapest at the minute. any reccomendations for companies or what % power i should be putting down are much appreciated!!
