Low quality and/or low octane fuel will greatly impact engine output and potentially even engine health. 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.įuel – Fuel quality is HIGHLY important with performance vehicles. 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. Naturally the C63 will show more gains as it starts at a lower level. Both have the same engine, but the C63 has 451hp while the CLK63 has 500hp. 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.
Actual gains are dependent on the following: Learn More about Crank HP Vs Wheel HP 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.
