The B9 2.0T A4 Ultra engine is a calm and fuel-efficient  power plant. Our Weistec W.1 ECU calibration allows the vehicle to feel more like a sports car rather than a fuel economy vehicle. Through testing on both the street and dyno, the ECU tune reliably extracts substantial gains in the top end.

Key Features:

  • Increased Boost
  • Optimized Fueling
  • Optimized Ignition Timing
*Power gains vary based on model, modifications, fuel, and running conditions.
