Mercedes-AMG C63 W205 — M177 4.0T V8 ECU Tuning & Performance Parts

The Mercedes-AMG C63 W205 runs the M177 4.0-liter twin-turbo V8 — one of the most tuneable forced-induction engines ever produced. Factory output is 469 HP (C63) or 503 HP (C63 S), but the M177 responds aggressively to calibration work. A Stage 1 ECU tune on stock hardware delivers 580–620 HP. Add catless downpipes for Stage 2 and you're looking at 650–700 HP with improved turbo spool and a significantly more aggressive exhaust note.

YPG Motorsport has been calibrating M177 engines since the platform launched. Our C63 W205 holds the world record for the first sub-10-second M177-powered C63 quarter mile — 9.97 seconds at 828 WHP, set at Beech Bend Raceway Park, Kentucky on April 9, 2019. The same ECU calibration expertise, turbo upgrade kits, and forged internals used in that record-setting car are available to order here.

What's available for the C63 W205: Stage 1 and Stage 2 ECU tunes delivered via YPG Flash (remote OBD) or YPG Bench (mail-in), catless and 200-cell GESI downpipes in 304 stainless steel with TIG-welded construction and CNC-machined flanges, Eventuri carbon fiber cold air intake systems, Stage 3 hybrid turbo upgrade packages with matched ECU calibration, Stage 4 race turbo kits rated to 1,200 HP+, M177 forged internals rated to 1,500 HP, and complete crate engine long blocks.
