Another Renault Megane came in for some serious track prep, and we pushed this manual 2008 Megane 2.0L Turbo to its limits.
Tuning this model presented a challenge due to the Sagem ECU, but using WINOLS, we edited the HEX file to raise the stock limiter from 5200RPM to 7000RPM, giving the car extended track capability and maximum performance.
Modifications & Upgrades
Larger Intercooler, Downpipe & Cold Air Intake – Optimized airflow and turbo efficiency
Removed Throttle Lag – Immediate response for track driving
Increased Radiator Fan Speed – Improved cooling under extended track conditions
Cam & Spark Timing Altered – Fine-tuned engine performance
Boost & Torque Limits Raised – Maximizing power output

Dyno Results
155kW at the wheels – With the supporting parts installed
181kW at the wheels – After our custom dyno tune
The result is a punchy, track-ready Megane with dramatically increased power and torque, built to handle the demands of performance driving.
📊 Check out the dyno graph to see the difference and the potential for even higher power and torque levels!
