1000 mile report after XC90 engine tuning

I love to bring an OLD thread back from the dead

In the past 7 years has anyone got anything more to add to this?

Thinking more towards the reliability of the Auto Boxes with all the extra torque.

I've just read this and appreciate it's from times gone by but the same arguments about chipping and informing insurance companies apply.

I've never chipped a car or modified one other than changing the stereo that I did declare (and they didn't care less) so I've no real opinion about declaring engine mods but something did occur to me while reading through the posts.

If you knowingly modify an engine and don't declare it then it should invalidate your insurance BUT what if you buy a used car which has been modified already and as you're not a car technician or expert you are not to know. When the insurance company asks if it has been modified when you take out insurance you'd say no in good faith. Where would things stand then as technically it has been modified and the new owner didn't declare it. The owner I guess would need to prove that he/she didn't do the mod themselves in the event of an accident and the mod being found by investigators.

This is why when I buy a new (used) car and the insurance company asks if it has been modified, I always answer "Not that I am aware off". I'm not committing insurance fraud then unknowingly and hopefully they would have me on record saying it should it be needed.
