We recently had a 2020 Mercedes-Benz GLE53 AMG in for our Stage 2 ECU + TCU performance package, and the results speak for themselves. With a platform as capable as the M256-powered AMG, it doesn’t take much to wake the beast — just the right tuning approach.

After our calibration and optimisation with Vaitrix Motor, the numbers jumped significantly:
📊 Stock Output (at the wheels):377.22 hp / 49.57 kg-m
⚡️ Stage 2 Output (at the wheels):434.45 hp / 62.04 kg-m

📈 That’s a +57.23 hp gain (~15%) and an impressive +12.47 kg-m torque (~25%). The biggest difference? Mid-range torque feels effortless now, and the transmission mapping feels tighter, smarter, and more responsive across all drive modes.
This is a street-friendly setup with OEM-level refinement, but a noticeable punch. No engine light. No drama. Just refined aggression.
