I’m not familiar with your particular model but there are plenty of reputable companies who will safely remap a diesel no matter what size it is. If you have high miles or your oil changes haven’t been done as they should then you can accelerate wear as is the same with any tuning.
It's a bit like Marmite. You're gonna get some that like it and say yes do it and some that don't and say don't do it! It's not gonna help your decision as some have horror stories and some have none. Just make sure if you do it's done with a reputable company.
