The OE Tuning MRC335 is a flashloader ECU tune specifically designed for the 2009-2011 Mercedes-Benz E350 equipped with the M272.983 V6 engine and the Bosch ME9.7 ECU. This tuning module is engineered to deliver a performance upgrade, providing an estimated gain of 17 horsepower and 17 lb-ft of torque, bringing the total tuned output to 306 HP and 287 lb-ft of torque. Beyond the core performance enhancements, the MRC335 offers several optional features to further customize the driving experience. These include the ability to remove Diagnostic Trouble Codes (DTCs), activate a "pop and bang" crackle map for an aggressive exhaust note, and options for DECAT (catalytic converter removal) and FLAPS (secondary air injection system) functionality. A Vmax (speed limiter) removal is also included. For those seeking an enhanced auditory experience, an optional "Exhaust Popping Feature" can be added. Installation requires a MyGenius programmer, which is available as an additional purchase.
