    Default Any way to tell if my car's been mapped at all?

    So I've had my Astra J for around six months now. I like it and all that. It came from a Vauxhall dealer under NetworkQ warranty so I expected it to be standard. It has however got a Maxton Performance splitter fitted, some carbon fibre wing mirror covers and the exhaust is loud, louder than another Astra j the dealer had in at the same time. Under the bonnet the air box had loose jubilee clips at either end of the pipe that comes out of it which I tightened but did wonder if something aftermarket had been replaced.

    So the big question is short of getting it on a rolling road is there any way to tell if it's been mapped at all? I'm unsure if it might be a remap on the standard exhaust or if Vauxhall might have reset a map it but maybe has a non-standard exhaust and along with all this what do I tell the insurance comapny? That's my main consideration, I don't want to find myself uninsured if I did have an accident.

    My expectations were that it would be stock as buying from a dealer but the more I think the more I wonder if someone's possibly done an indiction kit, maybe an exhaust and aftermarket body bits then why wouldn't they have done a remap too given the bang for your buck?

    Pretty sure only way to tell is by rolling road. Unless it can be plugged in a read what map it has? Not sure if it works like that though
