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.
