Overview

RennTech built its name in Florida tuning high-performance engines, and this ECU Hand Held Tuner for the 2002-2004 G 55 AMG is the result of in-house dyno development on the 5.5L M113 V8. 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 370 hp and 410 lb-ft with this upgrade.

Key details

The W463 G 55 AMG makes up to 380 hp and 410 lb-ft with this tune. The hand-held tuner switches between tuned and stock files as often as you like, with no need to remove the ECU.
