A remap won't kill your turbo. Your driving style will if you don't know how to treat them.
Give it the beans when the car is NOT warmed up and also not cooling your turbo down by coming off boost before you park up after it's been used strongly will ruin the turbo.
I never boot it until 20-30mins into a drive, and come off boost on my drives home way before the car switches off on the drive.
If you don't follow those steps or similar, your turbo will go mapped or non-mapped.
The alarm we have fitted (clifford) has a cool down button fur that purpose. Get random looks from people when walking away from a running car!
