Google does - ish. Bit "bonnet de douche" "duck ala orange" but better than nothing.. . 
Hello together!
I saw today the interesting entries about GTi edition 30 with Oettinger Tuning. In order to make it short, the gulf in the “good travel†(EN-AI 47) is my car.
In order to create here times a few facts:
1. The engine is from the AUDI S3, however factory-installed with a smaller LLK was provided.
2. The engine has hardly thing in common with series the TFSi, since it is completely strengthened, is had forging pistons and the compression different.
Hmm, I really don't know where this myth is coming from. The Ed30 does not have the S3 engine.
3. In series my GTI had already 250 HP on the Rollenprüfstand.
I doubt that - VERY MUCH. He is stating 250HP on a rolling road. As the Ed30 engine has a claimed 230PS (about 225bhp) at the flywheel, transmission losses would give a wheel horsepower (the HP figure he is claiming

) of around 180-190 HP - maximum. If he is claiming a "corrected" power output, then that figure should be quoted as "brake horsepower" or BHP. Even then, 250 BHP sounds a little "head in clouds" !!!

4. After the re-equipment of Oettinger 340 HP were measured. With this achievement the car runs however merciless into the speed limiter.
Again, some incorrect figures. Furthermore, the Golf does not have a speed limiter.

The standard LLK is at its power limit. Load air becomes too warm and the engine regulates down. In any case large LLk take.
A small intercooler does NOT limit power (unless it is internally restrictive and not free-flowing). A small intercooler will merely be more suseptable to "heat soak", and the power will drop off more noticeably than a correctly specified larger version.
By LLK must be talking about intercooler.
Yup
