Dyno Results

Final Output: 175HP / 189Nm

Despite the mismatched components and the loss of VVT advance, precise fuel and ignition mapping allowed recovery of strong mid-range performance. Load calculation, ignition strategy and fueling were optimized to ensure stable AFR control and a smooth torque curve.

The result confirms that even with sub-optimal hardware combinations, proper calibration can recover significant performance and drivability.
