What we do for the c63.

Stage 1 unlocks boost, timing, and fueling across the M177's broad envelope. The platform is shared with the C63, E63, GT, AMG GT, GT-R, and others — we've mapped the family extensively. Stage 2 with downpipes + intake + IC + flex fuel territory pushes well past 700 wheel hp.

Common questions.

Will Mercedes detect the C63 tune?

Some AMG ECUs log overboost events. We offer free stock-revert before any planned dealer visit.

C63 vs C63 S — different tune?

Same engine, different power maps. The S has a higher boost ceiling from the factory. We tune each as its own platform.

Will the 9-speed handle more power?

AMG Speedshift MCT handles Stage 1 and Stage 2 power. Built-engine + 800+ wheel hp territory may need transmission attention.

How long does the appointment take?

Stage 1: 2–3 hours. Stage 2 with mods to install: full day.
