R1 Performance Package for Mercedes-AMG GT63 4-Door Coupe: ECU Upgrade (HHT),Mufflers, Blow Off Valves (BOV), Exhaust Valve Module (EVM), BMC Air Filters

The Mercedes-AMG GT63 4-Door Coupe (X290) is powered by the latest V8 BiTurbo -engine developed by AMG, the company’s Affalterbach based performance division and long fabled engine builder. The result is nothing short of spectacular and the 4.0L V8 BiTurbo engine is an incredible platform to build performance upon.

RENNtech’s R1, R2, R3, and R3+ are vehicle specific performance packages, engineered to increase vehicle power output while ensuring all upgrades work in sync, resulting in optimal overall performance.

Increasing performance in stages offers a clear path toward the desired development goal or stage. Starting at R1, moving forward is easy and gives owners the ability to evaluate the impact of each level of modification through the stages. Owners can also plan and budget for additional modifications, making the ultimate build more affordable in the long run.

What is included in the R1 package:

ECU Upgrade: Our proprietary tuning module stores both the RENNtech tuned file and your vehicles stock file. The module plugs directly into the OBD2 port and delivers the file you choose directly to the ECU.
Stainless Steel (SS) Sport Mufflers: Made out of 2 3/4 inch diameter tubing our sport mufflers are lighter weight than the stock exhaust and improve performance by reducing exhaust back pressure, increasing exhaust gas flow and cylinder scavenging. Fully compatible with factory exhaust valves, for Comfort, Sport, Sport + / Race -modes.
Blow Off Valves: Designed as a quick bolt-in solution which are intended to release excessive pressure in high boost occasions.
Exhaust Valve Module: The EVM allows you to fully open the exhaust valves of the AMG Sport Exhaust, giving you complete control over the exhaust sound regardless of speed, RPM or driving mode.
BMC Air Filters: BMC air filters are designed to last longer and create better airflow than OEM paper filters.

*If not otherwise noted, performed on non-prepped asphalt and with OEM, Street-Legal and/or Non-Performance tires. Data measured with Racelogic Performance Box.The R1 Performance Package was developed and tested running on standard 93 octane gas.

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 AWD vehicles.
Numbers published by MBUSA are an average over a 750 rpm 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.

Performance Numbers Overview

AMG GT63 (MY 2019+) | X290 | M177 | 4.0L V8 BiTurbo Stock Performance (at crank):

Rated by Mercedes-Benz (avg.): 630 HP @ 5,500-6,500 rpm; 664 LB-FT @ 2,500-4,500 rpm
Dyno measured by RENNtech (peak): 681 HP @ 6,250 rpm; 736 LB-FT @ 3,450 rpm
- Note: Mercedes M177 engine performance when measured on the dyno obtains higher power numbers than rated from factory. Performance numbers published by MBUSA are a calculated average within a specific rpm range, which obviously result in lower power numbers than at the peak. HP and TQ gains calculated by RENNtech are always based on peak stock results measured by RENNtech and upgraded peak results measured by RENNtech.
- For transparency and comparability, RENNtech published the average stock power during the rpm range set by MBUSA and the peak stock performance

AMG GT63 (MY 2019+) | X290 | M177 | 4.0L V8 BiTurbo Modified Performance (at crank):

Rated by RENNtech (peak @crank): 793 HP @ 5,600rpm; 808 LB-FT @ 4,400 rpm
Rated by RENNtech (peak @wheel): 666 whp @ 5,600rpm; 679 wtq @ 4,400 rpm

Crank Performance Numbers are calculated with a 16% Drivetrain loss for all wheel drive vehicles.

The R1 Performance Package was developed to deliver maximum power running on standard 93 ocatane gas, adding convenience for track and street driving.
