Great Wall Motors (GWM) produces a range of SUVs and pickup trucks with turbocharged diesel and petrol engines. The Haval brand SUVs and the Steed pickup are the most common GWM tuning candidates in Europe.
The GWM Steed 5 and Haval H6 with turbocharged diesel engines offer ECU tuning potential. Results vary by ECU variant — diesel models typically show the best gains with +30–50 Nm achievable with proper calibration.
GWM/Haval tuning requires ECU identification before assessment. Contact us with your specific model and engine code for availability. We evaluate each vehicle individually.
