Hi everyone, Just wanted to share some feedback regarding DSG DQ250 tuning, as it may help others. On my Skoda Superb 3V EA888 Gen3 running E85 (around 365 hp / 460 Nm), I had been experiencing micro-jerks under full load and noticeable torque cuts around 6800–7000 rpm, even after doing proper VCDS resets and adaptations. The engine itself was running perfectly, but it was clear that the stock TCU strategy was no longer suited to the torque level. After doing some research, I contacted Kalam at Russell Road Racing (RRR), who works with Simos Tools. I can honestly say the service was excellent: professional, knowledgeable, and very responsive. After sending him my ECU, TCU, and Haldex information, he prepared a custom TCU file perfectly matched to my DQ250 version. The flashing procedure was straightforward (full flash), followed by a full VCDS recalibration. After installation and adaptations: * No more jerks * No more torque cut at high RPM * Much smoother gear changes * Gearbox now fully aligned with the engine tune * Much better driving experience overall Even after only a short learning period, the improvement was very noticeable. This is not a generic “stage” file, but a proper calibration based on the real setup and data. Clutch pressure and torque management are very well handled, without unnecessary harshness. For anyone running Stage 1+/Stage 2/E85 on a DQ250 and experiencing shift issues or torque intervention, I can genuinely recommend Kalam / RRR. This is proper engineering, not marketing. If anyone has questions abou t the process, feel free to ask. ---
