PART 2: NEW DEVELOPMENT 🔥 – BMW 320i B48 (RON97)
Factory output:
• 173.97 WHP
• 290.72 Nm
Current:
• 282.97 WHP
• 408.14 Nm
Gains:
• +109.00 WHP
• +117.42 Nm
Following the successful RON95 development, we further refined the calibration on RON97 fuel, unlocking substantially more power and torque while retaining factory-like drivability and refinement.
While the peak figures are impressive, the real highlight lies in the torque delivery. Producing over 400 Nm through the heart of the powerband, the car delivers noticeably stronger mid-range acceleration, sharper throttle response, and sustained pulling power all the way to redline.
The increased octane of RON97 allowed us to safely optimize ignition timing and overall engine calibration, extracting more performance without compromising reliability.
This development demonstrates the true capability of the B48 platform when paired with proper calibration, extensive validation, and quality fuel.
