RennTech built its name in Florida tuning high-performance engines, and this ECU+ Upgrade for the 2016-2019 GLE 450 SUV is the result of in-house dyno development on the 3.0L M276 twin-turbo V6. Timing, throttle, air-fuel and boost tables are revised as one calibration, so the car pulls harder everywhere while staying a comfortable daily driver. RennTech rates the car at 392 hp and 463 lb-ft with this upgrade. That is a gain of 30 hp and 84 lb-ft.

Key details

Up to 392 hp and 463 lb-ft, gains of 30 hp and 84 lb-ft, CARB certified for all 50 states. RennTech has tuned Mercedes engine computers since they first appeared in the mid-1980s, and the gains cover the whole rev range.
