At SL Autowerkes, we deliver tailored Stage 1 to 3+ performance upgrades designed to enhance power, responsiveness, and drivability — without compromising reliability. Whether you’re looking for a mild tune or a full engine build, our upgrades are engineered for precision and results.

What Are Stage 1–3+ Performance Upgrades?

  • Stage 1 – Software-only upgrade (ECU/TCU tune), ideal for stock vehicles.

  • Stage 2 – Software + supporting bolt-ons (intake, downpipe, intercooler, exhaust).

  • Stage 3+ – Larger turbo upgrades, fueling, engine internals, gearbox mods, and custom tuning.

Each stage is customised to your platform, driving goals, and power expectations — all while maintaining safety and drivability.
