Had mine from 42k miles.
Remapped @ 60k to stage 2 Giac software, remapped again @ 98k 2+ ish at Unicorn.
Now on 102k. Nothing has gone pop or bang yet, touch wood.
Original turbo etc (the only thing missing for stage 3 mind)
Intercooler and injectors have been found to be ready for sorting when I've been in there, but otherwise as you were... but some things were updated quickly... so might be a factor...
