If you own a late model Mercedes and want to improve on what Mercedes has already done, Renntech has the products you’ll want.
Renntech was founded in 1989 by Harmut Feyhl. Prior to opening Renntech, Harmut spent 12 years working at AMG Germany. Renntech has since evolved into North America’s foremost authority in Mercedes tuning. Even thought Renntech is a US based company, they stay true to their German roots with their research and development center located at the world famous Nurburgring to test their products in the real world and in the most grueling conditions possible.
Renntech offers a large selection of products across numerous Mercedes platforms. Their claim to fame is their ECU Upgrades
Renntech’s has been at the forefront of ECU tuning since electronic engine management started showing up in vehicles during the mid 80s. Renntech’s experience, countless hours of in-house research, development and exhaustive testing ensure that their proprietary ECU upgrade offers incredible performance gains and rock solid daily driver reliability.
Renntech’s tuning software for Mercedes offers significant gains in horsepower and torque across the vehicle’s 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.
To go along with their ECU Upgrades, Renntech also offers other bolt-on performance parts such as their carbon intakes, headers, exhaust systems, BOV adapters and more
Renntech also has a line of Aero parts available for certain vehicles to get a more aggressive look to match the aggressive performance of your modified Mercedes. Renntech offers everything from splitters, rear diffusers, carbon fiber lip spoilers to full DTM inspired carbon fiber spoilers and carbon fiber widebody kits
If you want to go to the absolute max with your Mercedes, Renntech’s Motorsports division pushes the limits of your Mercedes to create absolutely insane packages.
For example, if you own a 2014 + E63 AMG Wagon, Renntech Motorsports R3 Package brings the power of the vehicle up from the stock 502 hp and 536 ft/lbs of torque to an astonishing 697 awhp and 784 awft/lbs of torque and catapults the vehicle from 0-60 in just over 3 seconds. How many other wagon’s out there on the road make that much power?
Even if you don’t drive a performance model Mercedes, Renntech has products available from their ECU upgrades which offer better performance and fuel economy to their suspension modules to give your vehicle a sleek lowered stance.
