What is the best way to increase the horsepower of a Ford Fiesta?

I have a Ford Fiesta and want to tune it for more power. I've heard about different methods like ECU remapping, turbocharging, and upgrading air intake and exhaust. What option would you recommend for the best results?

I've personally had great results with ECU remapping. It's a relatively affordable and easy way to get a significant horsepower increase.

Turbocharging can definitely give you a big power boost, but it's also a more expensive and complex option. It really depends on your budget and willingness to modify your car.

Upgrading your air intake and exhaust can help with engine breathing and increase power, but the results may not be as dramatic as ECU remapping or turbocharging. I recommend doing research and considering your goals before making a decision.
