Ibiza 1.2 TSI CJZC — MED17.5.25 551368 Bosch — ECU Files
This is a comprehensive Stage 1 tuning package for the Seat Ibiza 1.2 TSI, equipped with the Bosch MED17.5.25 ECU. This package is designed to provide maximum flexibility and fun, containing multiple modified files to suit your preference, all calibrated for a stock vehicle.

The package includes a powerful Stage 1 tune targeting 130hp and 226Nm, which also removes the top speed limiter (Vmax). For those seeking a more aggressive sound, we also provide a standalone Pop & Bang file for a stock-power car, and a combined file that pairs the full Stage 1 performance with the exciting Pop & Bang overrun feature. This is the all-in-one package to transform your Ibiza.
