Ok the remap and cams I can see, because you don't know if they are there or not, but as Russ said, you haven't declares the bodywork changes (sport body kit etc)
Also you say you are a names driver, so are you the main driver or is the policy holder the main driver? As if you are the main driver then it is 'fronting' which is better known as insurance fraud.
I thought as much, that's why I couldn't believe an 18 year old insuring a 1.6 modded up to the eyeballs! I'm struggling to insure my 1.2 and that's not with all the mods declared yet! And I'm 19. It is all in my own name and policy though
