Yes there's always an element of risk associated with tuning your car. That is why if you're going to do it choose someone that has back-up/support if anything should ever go wrong.
Second thing I'd say for all the 162TSI guys is that your engine has been out in the Mk7 Golf GTI and Gen3 Skoda Octavia RS for quite a few years now already. The only major issue I'm aware of in the MQB platform engines was in the early Golf R/S3 206kW version which was killing turbos. However there's a revised part now that seems to be a lot more reliable and it's not the same engine in the Tiguan anyway (I know we are all wishing there was a Tiguan R).
There's quite a few Mk7 Golf GTI's running tunes without issues. If I had a new Tiguan I'd be waiting for 5,000-10,000km then getting a service with full check over to make sure there's no warranty issues (leaks, etc) then roll the dice and go for it. But yes there is an element of risk that you do have to take on when you do it. As the saying goes gotta pay to play.
