BMW X4 28i N20 (F-Series) – Stage 2 + Crackle Calibration | DMS TUNED

This BMW X4 28i (N20 turbo engine) already had solid performance, but the goal was to enhance both power delivery and exhaust character. A full Stage 2 calibration was completed, followed by a properly controlled crackle setup.

Stage 2 Calibration

  • Optimized boost control strategy
  • Revised ignition timing and fueling maps
  • Torque management refinement
  • Improved throttle response and mid-range pull

Custom Crackle Setup

The exhaust sound calibration was developed to provide controlled overrun crackles without compromising torque delivery or increasing exhaust gas temperatures beyond safe limits.

No excessive fuel dumping. No uncontrolled backfires. Just a clean, responsive system that reacts when you lift off the throttle.
