E63 AMG Stage 1 vs Stage 2

E63 AMG Stage 1 vs Stage 2 — Power, Cost & What You Need

The Mercedes-AMG E63 S (W213) with the M177 4.0-liter twin-turbo V8 and 4MATIC+ all-wheel drive is one of the most capable performance sedans ever built. With 603 HP from the factory, it’s already fast — but ECU tuning takes it to another level entirely. Here’s how Stage 1 and Stage 2 compare on the E63 platform.

Stage 1 E63 AMG

A Stage 1 tune recalibrates the E63’s ECU with optimized boost, timing, and fueling maps. No hardware modifications are needed — the car remains completely stock. The M177 in E63 S specification already runs higher factory boost than the C63 S, but there’s still significant headroom in the calibration.

Spec	Stock E63 S	Stage 1
Horsepower	603 HP	~680–700 HP
Torque	627 lb-ft	~680–720 lb-ft
Hardware	—	None required
0–100 km/h	3.4s	~2.9–3.0s

Stage 2 E63 AMG

Stage 2 adds catless or high-flow downpipes and a more aggressive calibration. The E63’s 4MATIC+ system hooks up the extra power brutally well, making this one of the fastest accelerating sedans on the planet.

Spec	Stage 1	Stage 2
Horsepower	~680–700 HP	~750–780 HP
Torque	~680–720 lb-ft	~750–800 lb-ft
Hardware	None	Downpipes, intake recommended
0–100 km/h	~2.9–3.0s	~2.7–2.8s

Which Stage for Your E63?

Stage 1 if you want serious gains with zero modifications. The E63 S with a Stage 1 tune and AWD is already faster than most supercars in a straight line.

Stage 2 if you want everything the stock turbos can give. With downpipes and a Stage 2 calibration, the E63 becomes a 2.7-second-to-100 sedan. There is nothing else like it on the road.
