Sport Performance Tuner

The DINANTRONICS Sport Performance Tuner (D440-0034) is an essential boost controller for the masses, designed for 2014-2020 Mercedes-Benz 2.0L Turbo Engines, specifically the C300, E300, and CLA250 models. This system features a simple, single-sensor design that allows for very quick and discrete installation. It utilizes built-in Bluetooth Smart connectivity for user-controlled adjustability and includes a live boost monitor via a smartphone app. The tuner precisely re-maps boost, fueling, and timing by leveraging the factory DME for optimal performance. Users can select from multiple power settings, including Sport, Sport+, and Race, or engage a Valet/Parental Control mode that reduces boost by 3 PSI. Performance gains are verifiable, with the unit delivering maximum increases of up to +30 HP and +40 lb-ft of torque. The tuner comes with the module and an application-specific wiring harness. It is backed by a 14-day satisfaction guarantee and a Manufacturer's 1-Year Product Warranty. Note that the DINANTRONICS Sport App is not compatible with Android OS 8.0 (Oreo).
