Does Stage 1 Tuning Have a Significant Impact on the Car?

Stage 1 tuning does not have a significant impact on the car, but it does have certain effects. Stage 1 tuning refers to enhancing the car's power by modifying the ECU software parameters without altering the hardware. Specifically, Stage 1 tuning involves adjusting the engine's parameters, primarily the fuel injection and ignition timing, to improve the engine's performance. After Stage 1 tuning, there are also certain requirements for the fuel quality used. The gasoline quality needs to be higher, as using low-quality gasoline after tuning can cause damage to the car to some extent.
I think stage 1 ECU remapping has a significant impact on cars. On the positive side, it can increase horsepower by 20%, making acceleration feel much more aggressive, almost like adding a turbo to the engine. Overtaking in city traffic becomes effortless. However, there are downsides too: fuel consumption rises by at least 10%, especially in stop-and-go traffic. Engine components like pistons and connecting rods endure higher stress, and without proper high-temperature protection, overheating and failure become risks. I recommend beginners avoid DIY attempts—always go to professional tuning shops for proper remapping and consider upgrading intake/exhaust systems too. While car modding is fun, never cut corners with pirated software, or repair costs could far exceed fuel savings.
