Hello Ulf,
The vehicle registration was processed without any problems (but the technical inspection report indicates a lower engine output).
Initially, the input threshold was set lower than it is now, which resulted in a feeling of increased power because it delivered a more impactful sensation. The gas intake was surprisingly good, but unfortunately, so were the exhaust emissions and tire wear.
'I had the ECU reprogrammed in the summer, and the exhaust timing remained the same. Now it drives like the stock configuration, but with a higher power output starting at 1600 RPM. The engine runs much smoother. The extra power is now regulated later, when the turbo boost is already present.' The gas consumption is the same as the standard.

Screenshot of the programming software, check out OBD-Tuning (JetBooster4), it's the same. I don't know if the box has the same design as the HOPA.
