Hi Optimus prime!
I added a DTUK box to my Manual GTD after it's first service (10,000 miles) and have since done another 11,000 problem free miles with the box on.
I never run the box higher than +1 (I use 3+1 or 1+1 only).
I think either a box or remap
could cause clutch slip, as you are putting a lot more torque through the drivetrain - but I've never had any and the DTUK delivery is very smooth. Personally I chose a tuning box as I can remove it for services and I was concerned a remap might cause TD1 flag's which
could have a negative impact on warranty issues.
The DTUK box also had loads of great reviews and lots of thorough testing and analysis here, especially by MonkeyHanger.
I don't think there is a right or wrong answer as to which solution is best as it will depend on what you consider a risk or not/your preference. If there are multiple clutch issues reported with Carbon, that's a bit concerning - but you could speak with them to see what circumstances the issues were in (manual/dsg/an older map??)
Either way, I do recommend a box/remap - the GTD was built for it
