My Toyota Sienta was consuming a lot of fuel at about 13.5km/l despite routine maintenance. After doing stage 6, my car was feeling more responsive and light. Just after 1 trip post catalytic converter clean, the car was consuming at only 18.6km/l!! Very huge difference! It was very smooth like butter! Now driving is so fun and really enjoyable!!

A quick one-month update. The car continues to deliver a very pleasant and enjoyable driving experience. Gear changes remain smooth, idling vibrations are minimal, and the overall drive feels solid. The biggest surprise is the fuel efficiency — 7.4L/100km. I genuinely never expected this from a 1.6-tonne executive sedan with a turbocharged petrol engine. Previously averaging around 13.1L/100km. Thank you, Gewinnen.

Was skeptical when I first saw it on FB. But I decided to take the leap of faith. Got to say this has to be the best decision ever. The Nano Bros are both skillful and have extensive knowledge on cars. After a few days of installing, I can totally feel that the car is way lighter than it originally was. Slight press and the acceleration is there. Money very well spent — I'm likely going to come back with more stages!
