Torque gain Up To
+0 TQ

Advertised gains are estimates of HP and Torque “at the engine” calculated from gains as measured on a Dynojet Dynamometer in ideal conditions and typically show the largest possible change. Actual gains are dependent on the following: Learn More about Crank HP Vs Wheel HP

Model – Manufacturers use the same engine in multiple model vehicles and often times they are in a different state of tune, for example: 2008 C63 and a 2008 CLK Black Series. Both have the same engine, but the C63 has 451hp while the CLK63 has 500hp. Naturally the C63 will show more gains as it starts at a lower level.

Model Year – Similar to above, as time progresses, Manufacturers tend to slightly increase power output via software from one year to the next or offer “Performance Packages” with increased power. The engines remain largely unaltered and as a result, final tuned output remains the same, while the gains are lower as the starting point is now higher.

Fuel – Fuel quality is HIGHLY important with performance vehicles. Low quality and/or low octane fuel will greatly impact engine output and potentially even engine health. Top tier brand premium fuels should always be used to achieve the best results possible.

Drivetrain – All wheel drive has higher drivetrain losses than rear wheel drive. This results in lower numbers when testing on a chassis dyno. Wheel/tire size and weight will also impact chassis dyno results

Weather/Conditions – Temperature, humidity, altitude, and air density all impact engine performance. Heat, high humidity, and thin air will all work towards reducing engine output

Engine Health – Higher miles tends to result in increased build up and lower compression which can and will impact engine output. Properly maintained engines will have better performance than abused or neglected engines.

Supporting modifications – The highest power levels require supporting modifications. Depending on the engine, this could mean forged internals, built transmission, upgraded fuel system, 110+ octane race fuel, etc.

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 firmer 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.
