TDI Tuning: Performance & Optimization

Hello everyone in the forum,
I hope I'm in the right place; if not, please correct me!

I found some information about tuning for TDI engines about half a year ago, but unfortunately, the search function isn't working properly for me. I would appreciate it if you could help me out briefly.

1. Nozzle tuning (I believe the larger injectors from the T4 were used?).
Adjustment of pump settings.
3rd-century tuning.
4.BOX od. Chip tuning.
5. Modify turbocharger (VNT17).
6. and so on!

As far as I know, most of them were still from Uwe, unless I'm mistaken.
Therefore, I would prefer not to reintroduce discussions about topics that have already been discussed.
I bought a TDI Galaxy because it was cheap, and now I want to modify it.

Best regards,
Little baby

So, the search function here seems to work fine (as long as you enter the correct terms). If it doesn't, please email our landlord.

Alternative for most of your topics: expert articles.

And be careful not to make a social faux pas number 2...

Warm welcome!

The search already yields 501 results when I just type the word "nozzle." So, please read carefully; there's a lot of information in there. Also, Ulf has already directed you to the specialized articles that will provide more details.
Here's another helpful tip for the future: Write down the engine code letter of your new car. It makes things easier for everyone.

Hello,
Thanks to you both, Ulf and matthiasTDI96.
Okay, under 'articles,' got it! I'll start searching right away.

Okay, so the engine type is WGR, with code AHU, and it's supposedly identical to the 1Z, right? It has 90 horsepower.
