C300 Tune — Stage 1

AMR Performance develops C300 software as 5 separate files, not one calibration reused across a range. The list includes ECU calibrations and transmission (TCU) software, which can be run individually or together. Installation is wireless via comport ipro (obd) or comport pro -or- dealer flash. These cover the C-Class (W205), C-Class (W204) chassis, each written for that car's engine and gearbox combination. All current files are built for 91/93 Octane pump fuel — no race fuel and no hardware changes required. Every calibration listed here ships as a Stage 1 tune; the power figures for each are on its own product page.
