3.0T SUPERCHARGED STAGE 1

The Stage 1 ECU program boosts power up to 416 hp and 391 lb-ft, transforming your supercharged 3.0-liter engine into a true performance-class car. Designed to work with entirely stock hardware and compatible with basic upgrades (intake, exhaust, intercooler) without reprogramming.

STAGE 2 SINGLE PULLEY

Stage 2 single pulley files are calibrated for a smaller supercharger pulley, producing up to 492 hp with only minor hardware upgrades. This is achieved by spinning the supercharger faster using a smaller pulley.

Recommended pulley:

  • Type: Supercharger press-fit pulley

  • Part: IEBAVJ1C

  • Size: 57.5 mm

  • Final ratio: 2.8217

STAGE 2 DUAL PULLEY

Maximize the full potential of the factory supercharger by combining a smaller 57.5 mm supercharger pulley with a 188 mm crankshaft pulley – or use a 207 mm overdrive crankshaft pulley alone to achieve up to 548 hp!

Recommended combinations:

  1. 57.5 mm supercharger pulley + 188 mm crankshaft pulley → ratio 3.2695

  2. 207 mm crankshaft pulley alone → ratio 3.2753

HARDWARE RECOMMENDATIONS

  • DSG tune / clutch upgrade: mandatory for dual pulley setups

  • Air intake: strongly recommended for dual pulley setups

  • Intercooler upgrade: mandatory for dual pulley setups

  • 57.5 mm supercharger pulley: mandatory for single pulley setups, mandatory with 188 mm crankshaft pulley

  • 188 mm crankshaft pulley: mandatory with 57.5 mm top pulley for dual pulley setups

  • 207 mm crankshaft pulley: mandatory with stock top pulley for dual pulley setups

  • HPFP upgrade: strongly recommended for E40 use

  • Throttle body upgrade: strongly recommended for dual pulley setups

DUAL PULLEY E40 ETHANOL

The E40 ethanol blend contains more oxygen, burns cooler, and resists knock better, allowing for significant power and torque gains. The factory fuel system and upgraded HPFP support the blend (2/5 E85 + 3/5 91/93 gasoline), yielding up to 548 hp and 525 lb-ft.

ADDITIONAL FEATURES

  • Increased rev limiter: 7200 RPM (Stage 1 & Stage 2 single pulley), 7350 RPM (dual pulley) – requires DSG tune

  • 2-step launch control: Improved acceleration launches, available for single pulley setups and included in dual pulley files

  • Exhaust crackle: Sporty sound effect, included in Stage 2 single & dual pulley setups

  • Fuel drain: Easy fuel switching for racing use

  • Manual fan control: Keeps the supercharger cool during race starts

  • Catalytic converter EGT optimization: Protects expensive catalytic converters by keeping exhaust gas temperatures in check
