Mercedes-AMG GT / GTS / GTR (C190 · M178 4.0L Twin-Turbo V8) — Complete Stage 3 Power Package
The complete Stage 3 build for the AMG GT platform in one SKU: 1000 HP+ capable turbo upgrade, catless downpipes, and a custom ECU calibration matched to the full hardware stack. Everything ships together — no sourcing parts from three different vendors.
What's Included
- Stage 4 Turbo Upgrade M177/M178 — full-billet precision-engineered turbo solution rated for 1000+ HP. Drop-in fitment, factory-matching wastegate actuation.
- AMG GT / GTS / GTR Catless Downpipes — mandrel-bent stainless steel, direct bolt-on replacement for factory catalytic converters.
- Custom ECU Calibration — YPG-developed Stage 3 turbo-matched calibration delivered via YPG Flash or YPG Bench. Boost targets, fuelling, ignition timing, and torque limiters all revised for the upgraded hardware stack.
Why Buy the Package
Ordering components individually means coordinating three separate shipments, hoping the tune matches the hardware, and paying full retail on each piece. The Stage 3 Package bundles everything at a package price with a single calibration file purpose-built for this exact combination.
GCC Shipping
The complete package ships via FedEx International Priority from our Kuwait workshop. Typical transit: 1–3 business days across the GCC, 3–5 days worldwide.
