Modern performance vehicles are already highly engineered from the factory, but electronic throttle mapping and conservative engine calibration can leave additional responsiveness and performance on the table. DTE Systems offers a range of vehicle-specific tuning solutions designed to address both areas, from throttle-response optimization with PedalBox to ECU-parameter optimization with PowerControl X and PowerControl RX.

The four products in this lineup cover applications ranging from the Mercedes-Benz CLE, E-Class, GLE, GLS, and S-Class to the BMW M2 CS and Volkswagen Jetta, providing different approaches to improving acceleration, throttle response, and overall driving characteristics.

DTE PedalBox: Sharper Throttle Response Without ECU Tuning

The DTE PedalBox is designed for drivers who want a more immediate accelerator response without modifying the engine's ECU calibration. Instead of increasing horsepower or torque, PedalBox optimizes the relationship between accelerator-pedal input and the vehicle's electronic throttle response.

For the Mercedes-Benz applications covered by the DTE10723765, the system provides 28 customizable response settings across four driving modes.

Four Driving Modes and 28 Settings

PedalBox provides four distinct driving profiles, each with seven fine-tuning levels:

• Sport Plus: Maximum accelerator responsiveness for an aggressive driving experience.
• Sport: Faster and more dynamic throttle response for spirited driving and overtaking.
• City: Smoother response for urban driving and stop-and-go traffic.
• Standard: Returns the throttle response to the original factory curve.

The integrated memory function automatically retains the last-used setting, so the preferred configuration is available each time the vehicle is driven.

Plug-and-Play Installation

PedalBox is designed for straightforward installation without ECU coding, smartphone pairing, or specialized tools. Installation takes approximately 15 minutes or less, with settings controlled directly through the device.

The system also features DTE's PerfecTune setup function, which individually optimizes the available response modes for the specific vehicle application.

Mercedes-Benz Fitment

The DTE PedalBox is designed for:

• 2024–2026 Mercedes-Benz CLE 53 AMG
• 2025–2026 Mercedes-Benz E 53 AMG
• 2024–2026 Mercedes-Benz E 450
• 2020–2026 Mercedes-Benz GLE 450
• 2026–2027 Mercedes-Benz GLE 53 AMG Hybrid
• 2020–2026 Mercedes-Benz GLS 450
• 2021–2026 Mercedes-Benz S 500

Always verify the exact vehicle, model year, engine configuration, and DTE application before ordering.

DTE PowerControl RX for the Mercedes-Benz GLE 53 AMG Hybrid

For drivers looking for more than throttle-response optimization, the DTE PowerControl RX for the 2026+ Mercedes-Benz GLE 53 AMG Hybrid provides a more comprehensive performance upgrade.

The vehicle-specific tuning module delivers up to +101 BHP and +102 lb-ft of torque, according to DTE, while using advanced multimap technology to tailor the power delivery to different driving conditions.

Three Performance Modes and 21 Adjustments

PowerControl RX provides three selectable modes with seven fine-tuning levels each:

• Sport: Maximum performance and responsiveness.
• Dynamic: Energetic and balanced response for everyday driving.
• Efficiency: Calibration focused on fuel economy.

The system can be controlled through DTE's dedicated iOS and Android smartphone application, allowing drivers to switch modes, adjust settings, view live performance instruments, and access features such as the warm-up timer.

Vehicle-Specific Calibration and OEM-Friendly Operation

PowerControl RX uses multichannel, multiprotocol hardware and vehicle-specific calibration to optimize key engine parameters, including the air-fuel mixture.

The system is designed to retain the vehicle's factory protection strategies and can be returned to its original stock configuration in minutes. Vehicle-specific wiring harnesses and installation instructions are included for the Plug & Play installation.

The GLE 53 AMG Hybrid application is rated for:

• 2026+ Mercedes-Benz GLE 53 AMG Hybrid
• Up to +101 BHP
• Up to +102 lb-ft of torque

DTE also backs the PowerControl RX with a 5-year warranty and 30-day satisfaction guarantee.

DTE PowerControl RX for the BMW M2 CS

The 2026 BMW M2 CS receives its own vehicle-specific DTE PowerControl RX application, offering increased performance while maintaining the same multimap and OEM-friendly approach used across DTE's advanced tuning range.

For the M2 CS, DTE states gains of up to +67 BHP and +68 lb-ft of torque.

The additional output is designed to improve acceleration, midrange performance, throttle response, and in-gear acceleration without sacrificing everyday drivability.

Tunable Performance for the M2 CS

The PowerControl RX uses three driving modes with seven adjustment levels each:

• Sport: Maximum performance.
• Dynamic: Balanced and energetic response for everyday use.
• Efficiency: Optimized for fuel economy.

Drivers can adjust the system through the DTE smartphone application, with access to live performance instruments, warm-up functionality, and on-demand mode switching.

Plug & Play and Reversible

The BMW M2 CS application uses a vehicle-specific harness and does not require specialized tuning equipment or a tuning-shop visit for installation.

PowerControl RX is designed to retain factory protection strategies and can be reverted to the original stock configuration when required.

The system is TÜV-certified, built and tested in Germany, and backed by DTE's 5-year warranty and 30-day satisfaction guarantee.

Choosing the Right DTE Solution

These four DTE applications are designed around different performance objectives.

The PedalBox is the straightforward choice for drivers primarily looking to improve accelerator response without increasing engine output. It focuses entirely on throttle characteristics and offers 28 response settings.

The PowerControl X and PowerControl RX systems take a more comprehensive approach by optimizing engine parameters to increase horsepower and torque while also improving responsiveness and power delivery.

Whether the goal is sharper throttle response in a Mercedes-Benz, additional performance for the BMW M2 CS, stronger output from the Mercedes-Benz GLE 53 AMG Hybrid, or a more responsive Volkswagen Jetta, DTE's vehicle-specific tuning systems provide Plug & Play solutions designed around modern electronic powertrains.

Important: Always verify exact vehicle fitment, model year, engine or powertrain configuration, and the applicable DTE part number before ordering.
