That's pretty much what I thought, and already researched the K03s

Is it an issue to re-map first, turbo later?
What happens when the turbo gives up? Just lose a lot of power?
If I remap now, will that be specific to the K03 fitted, or is it specific to the ECU so will work with the K03s too? There's no point paying out for a remap if I have to then remap again with a new turbo on.
Oh and where is the DIY guide on replacing the turbo
