🛠️ Software Features

Full Emissions Solutions: Level 2 and Delete calibrations include professional deactivation of DPF, EGR, and SCR (AdBlue) systems. This permanently resolves the "No Start" countdown and sensor failures.
Twin-Turbo Optimization: We refine the transition between the small (high-pressure) and large (low-pressure) turbochargers for a seamless, linear surge of power across the entire RPM range.
Refined Transmission Logic: Our torque mapping is synchronized with the 7G-TRONIC transmission to ensure smooth shifting and durability under increased torque loads.
Safety Protocols: All factory engine protection logic (EGT monitoring and Oil Temperature fail-safes) remains 100% active.
