How much horsepower can a Volkswagen 1.4T engine gain from a stage 1 tune?

Volkswagen 1.4T engine gains 50 horsepower from a stage 1 tune. Definition of horsepower: Horsepower is a commonly used unit of power measurement in engineering, proposed by James Watt. 1 horsepower is approximately equal to 735 watts. It generally refers to metric horsepower rather than imperial horsepower. Role of horsepower: Higher horsepower in a car means greater traction, resulting in shorter acceleration times and better dynamic performance. In trucks, greater traction allows for carrying more cargo. Horsepower is determined by the engine, transmission, and drivetrain together. Higher horsepower means faster acceleration, with maximum horsepower achieved at lower gears during driving. The top speed depends on factors such as engine power, vehicle weight, and transmission gear ratios.
My Golf is the 1.4T version, which originally had only 131 horsepower before the Stage 1 tune. I later took it to a local professional tuning shop for ECU remapping. The result was noticeably stronger acceleration when stepping on the gas, and the shop said it could reach around 160 horsepower, with even more torque gain. However, I should remind you that the outcome depends on the car's original condition and fuel quality—I had to switch to 98-octane gasoline for stable performance. It's much more fun for overtaking in the city, though fuel consumption increased by about 0.5L/100km. It's best to check the turbo and cooling system beforehand—my friend skipped this and ended up with high intake temperatures affecting performance. Overall, it feels like a 25% improvement, and spending a few thousand bucks was totally worth it.
