APR tune for the 2013+ Touareg TDI

Has ANYONE, I mean EVER, had an APR tune done on their VW Touareg TDI 2013+..

If so: Do you like it , -meh- , or don't do it at all.

Wondering about this for AFTER the powertrain and extended VW warranty is gone.

We aren't much for APR around here. Their tunes for diesels have never been much despite how well they do on the gassers.

They also don't support the TDIclub community in anyway, posts, tech etc. Look at the vendors who do post here for more than just their own 5% off FS threads.
