RENNtech ECU+ Upgrade | V167 | 745HP / 767LB-FT | 4.0L V8 BiTurbo EQ Boost | M177 | for Mercedes-Benz GLE 63 AMG BiTurbo 2021-2023

RENNtech HHT (Hand Held Tuner) allows you the unlimited ability to switch between tuned and stock ECU programming without ECU removal!

RENNtech’s proprietary tuning module contains both the Tuned file as well as your vehicles Stock file. The module plugs directly into the OBD2 port and delivers the file you choose directly to the ECU. Programming takes only a few minutes and the vehicle can be re-flashed at any time as many times as you wish.

With the proprietary RENNtech ECU Tuning the X167 - GLS 63 AMG Coupe EQ Boost gains up to +97 HP and +54 LB-FT, based on power numbers measured by RENNtech. Please note that the Mercedes M177 engine performance when measured, obtains higher numbers than rated from factory. The maximum power number reached with the RENNtech ECU Upgrade for the GLS 63 S AMG EQ Boost+ is 745 HP and 767 LB-FT

Notes:

  • We have found the M177 engine stock performance numbers vary from the baseline figures claimed by Mercedes-Benz. We typically see higher baseline numbers than claimed by the factory.
  • Power gains are calculated based on stock numbers measured by RENNtech. Crank Performance Numbers are calculated with a 16% Drivetrain loss on 4MATIC+ vehicles.
  • Numbers published by MBUSA are an average over a 750rpm range for HP and a 2,000rpm range for TQ. Power gains are calculated based on the peak stock performance measured by RENNtech.
  • Our numbers will be dependent on conditions and fuel quality. 93+ Octane gasoline is mandatory with this Performance Upgrade.
  • States known for poor fuel quality have to be supplied with a lower power setup. Please call for details and Race fuel options +1-561-845-7888.
