My car is on 96 000 km now and when MP runs out I want to EGR bypass and eventually take out the DPF and do a bit of software. How does this affect insurance?
Interesting topic. If I mod the tractor (if I still have it by the time MP expires) I will also rather declare this, even if my premium goes up - no way I am waiving an insurance claim against a few mods.
I guess you need to do the same when fitting the PPKs?
