It's a marketing tool, because if they say the real job of throttle controller is to eliminate throttle lag, who's going to

pay for that? No one will! But if they say it can increase power by 60%, they can seduce a large number of people's interest! And after installation, you really can find your car is much faster, so a lot of people believe! And normally many driver will not measure the maximum power and torque, so all throttle controller companies say it can increase power!That's why many drivers despise it! Because they knew the manufacturers were lying and exaggerating the throttle controller!

We started from the principle of throttle controller. It can only control the throttle opening speed. We know that the

throttle is actually same as gaspedal. When pushing gaspedal slowly, throttle opens slowly. When pushing gaspedal fast, throttle opens fast. The old cars before 2005 are wire throttle, which connect with gaspedal through a wire. How much you push gaspedal is same time as throttle opening. So you don’t feel throttle lag and speeding up is quite linear. But today's cars are all electronic throttle, what you push is actually a signal which will spread to throttle ECU and transform to throttle. So you’ll find when you push gaspedal, acceleration comes a little bit slow. This is an electronic throttle car disease: throttle lag. The role of the throttle controller is to solve the throttle problem!

Although throttle controller is not as necessary as oil and tires, actually it is in great demand in the market. And the sales of throttle controller at home and abroad are increasing every year. It doesn't make any changes to the original car, but it does significantly improve the driving experience. We all know that most of car tunings will lose their warranty, but throttle controller doesn't, because it doesn't change anything about the original car. For fresh car tuning enthusiasts, installing a throttle controller saves a lot of worry. Therefore, we should have a rational attitude towards throttle controller. It’s not omnipotent, and it’s not useless. No increasing power! Just only speed up the throttle response and eliminate the throttle lag! As a refit, throttle controller is easy to install and can be done by yourself in a few minutes, which greatly reduces the threshold of refit, compared with the deep refit such as tuning the ECU and exhaust pipe.
