This tuning pack for the 2004 Mercedes S600 (W220) offers two calibrated power stages for the 5.5L V12 BiTurbo running on Bosch ME2.7.1. Delivered as raw eprom binary dumps, it includes the untouched factory file, a refined Stage 1, and a high-output Stage 2 with aggressive torque and boost maps. Ideal for retro ECUs, this set targets those looking to awaken true potential from the M275 engine while retaining safe operational margins.
