Product Description


ATTENTION! This tune is only available in person at Weistec in Anaheim California or select Cypher Pro Dealerships. Contact Us for more details.

Some Audi models may have variants that come equipped with a 7-speed DCT Transmission instead of an 8-speed automatic. Please make sure your vehicle has the correct transmission for this tune before purchase.

What is a TCU Tune?

The TCU (Transmission Control Unit) is a computer that controls how the transmission operates. By tuning the TCU we change how the transmission puts down power. The Weistec TCU tune results in faster and more firm shifts. This is accomplished with faster target shift times and running higher line pressure which also has the added benefit of reducing slip and increasing the torque capacity of the transmission. With higher line pressure, the clutches in the transmission are clamped harder making for better grip which directly allows the transmission to hold more torque. With less slip and faster shifts, the lifespan of the transmission is typically improved as well. This is a great upgrade for a stock or modified vehicle because the improved power transfer from the engine to the wheels changes the dynamics of the vehicle. This allows you to experience the full potential of all your existing performance upgrades.
