Our proprietary ECU upgrade for the Mercedes M157 engine offers huge gains in performance across the entire RPM range without sacrificing around town comfort or daily driver reliability.

Our ECU tune offers the biggest performance gains on the market; increasing performance from 550 HP and 560 lb/ft torque, to an astonishing 633 HP and 656 lb/ft at the crank! This allows the M157 engine to run the quarter mile in an impressive time and dramatically improves 0-60 mph times.

• Note: We have found the new M157 engine stock performance numbers vary from the baseline figures claimed by Mercedes Benz. We typically see slightly higher baseline numbers than claimed by the factory.

GL 63 (X166) Stock Performance:

• 550 HP @ 5250 RPM; 560 LB-FT @ 2000 RPM

Modified Performance:

• 633 HP @ 5500 RPM; 656 LB-FT @ 3800 RPM

The RENNtech V3 Digital Lowering Module (DLM) is designed to work with all available Mercedes Airmatic or ABC (Hydraulic) Suspensions.The unit allows the user to have full control over all four corners of the vehicle’s suspension and adjust in 1mm increments.
The DLM requires no splicing or soldering to the factory wiring harness. The RENNtech harness utilizes the factory pins as to allow a completely reversible installation.
The unit also supports speed-dependant lowering that allows the vehicle to return to its factory ride-height at a pre-set speed. This removes the need for the vehicle to be aligned after lowering. The user can maintain the factory longevity and still have the lowered look at low speeds!

All RENNtech DLMs are adjustable via USB using either Windows or Android OS.The software allows the user to adjust the ride-height at each corner in 1mm increments independently.The software also has three locations where the user can store pre-configured suspension setups for quick changes.

• Please note: On the SL 550 (R231) the ABC suspension system is optional equipment from the factory. The ABC suspension system is required for the digital lowering module (DLM)
