PDE: Bigger is Better?

Translated on 09-09-2026, 4:22.

hello

I drive a Golf with an ARL engine (110 kW) and want to increase its power. I had a company in mind that offers pretty much everything for TDIs, such as turbochargers, downpipes, engine displacement upgrades, LLK (intercoolers), and larger PDEs (fuel injectors) than mine. I think most people know which company I'm talking about, even without me writing the full name: Gru... Mo..., I don't want to offend anyone. However, I can't reach anyone at that company. Do you know if they still exist, or what kind of work they do? And can you get those larger PDEs anywhere else?
I am grateful for any tips.

best regards, christian

Just tell me who you mean.

Half of your contribution consists of describing a store, of which you don't even know if it still exists. The name and any URL you know would be shorter

.

Then the others could probably help faster too - that's the point of the forum.

I don't think there's anything wrong with asking openly here.

As long as you don't just write something like: "Wow, *** is great, awesome tuning and stuff -> www.der-***.de", it shouldn't be considered as disguised advertising.

(I specifically chose to mention

because everyone knows about them, so it can't be considered advertising from me.)

Greetings.

hello

Okay, the company is called all4tdi.de, formerly Grundler Motorsport. Has anyone had any experience with them, or do you know if they still exist? When I spoke to them on the phone a few months ago, they were in the process of moving to Mannheim. I'm also interested in hearing opinions about their products.

Hmmm, you already have the large PDEs, or are you interested in an even larger 'small series' of elements?

Okay, it's about the small-batch PDE (presumably a product designation), the software, and the revised GT20 turbocharger (which might just be a smaller exhaust housing). Are there any people here who know the company from personal experience? I mean, surely there must be more people interested in the larger PDEs.
