RENNtech has been at the forefront of ECU tuning since electronic engine management started to show up in vehicles during the mid 1980s! Our experience, countless hours of in-house research, development and exhaustive testing ensure that our proprietary ECU upgrade offers incredible performance gains and rock solid daily driver reliability.
RENNtech tuning software for Mercedes offers significant gains in horsepower and torque across the vehicles entire power band. By modifying ignition timing and throttle mapping, optimizing air-to-fuel ratios, increasing the engine's rev limiter and modifying boost mapping for turbo-charged vehicles, RENNtech performance software unleashes the true potential of your Mercedes.
With the proprietary RENNtech ECU Tuning the W205 - C 63 AMG gains up to +56 HP and +107 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 fot the W205 - C 63 AMG is 601 HP and 657 LB-FT.
RENNtech Sport Mufflers are made out of T-304 stainless steel (SS) and 100% hand crafted in the USA. This exhaust system is rigorously tested to remove any unwanted resonances in the cabin to deliver a deep sound that keeps with the character of a luxury performance vehicle.
Our mufflers with 2 3/4 inch diameter tubing offer lighter weight than the stock exhaust and improve performance by reducing exhaust back pressure, increasing exhaust gas flow and cylinder scavenging. The RENNtech Sport Muffler System for the W205 - C 63 AMG Sedan comes with an integrated valve system and utilizes the electronic OEM actuators. The system comes with all the required hardware.
The RENNtech BOV | Blow-Off Valve Adapters are designed as a quick bolt-in solution which are intended to release excessive pressure in high boost occasions. While releasing the pressure, the RENNtech BOV adapters create the on turbo-charged engines well-known "blow-off" sound. CNC machined out of 6061-T6 aluminum, the RENNtech BOV adapters are anodized in black and laser-etched. Due to utilizing the OEM electronic diverter valves, the RENNtech BOV adapters will not trigger the Check-Engine light.
The full set comes with 2 BOV adapters, 4 o-rings, 6 stainless steel bolts and an allen-wrench. The BOV adapters work perfectly in combination with the RENNtech ECU Upgrade, due to the adjustments to the electronic OEM diverter valves.
