A Stage 1 ECU tune can certainly enhance your car’s performance if done correctly. A basic Stage 1 tune is unlikely to impact the life of the engine or gearbox, as these components are built and tested to tolerate much more than the factory specifications.
However, the ECU in the Skoda Slavia 1.5 TSI is locked, and for a long time, most Indian tuners have not been able to bypass it. Some tuners are working around this by installing an unlocked ECU from the T-Roc 1.5 TSI, but this method is considerably more expensive than a regular Stage 1 remap.
If you decide to go ahead, proceed with caution and choose a well-established tuner with proven expertise.
