We put the Changan CS55 with the MG1US008 ECU on the dyno.
The first version of the tune gave us an extra +30 hp and +70 N·m at the peak compared to stock (check out the photo).
The customer wanted more, so with the second version, we ended up with +55 hp and +80 N·m.
But here’s the real deal—it’s not just about the peak numbers. The significant torque gain in the 2000–4500 RPM range makes for a much stronger pull and way better real-world performance.
P.S. Dyno graphs are posted exactly as they came out—no touch-ups or corrections.
