• Bootmod3 OTS Stage 1 ECU Calibration (BM3 licence included). A proven Stage 1 tune from Bootmod3, designed for stock hardware and 98/99 RON fuel (e.g. Tesco Momentum or Shell V-Power). Developed by ProTuningFreaks, this map offers a safe and effective increase in performance with factory-level refinement.

• FJM Stage 3 TCU Calibration (XHP Gearbox Map). Sharpened shifts, quicker paddle response, raised torque handling, and true manual mode (no forced upshifts). Essential for pairing with increased engine torque and getting the most from the 8-speed ZF gearbox.

• Optional: FJM Performance Drop-In Filters. High-flow filters designed to fit within the OEM airboxes. Improves airflow without compromising comfort or reliability. A simple, effective support mod for tuned applications.
