Would like to ask some information sa mga motorist/hobbyist from here that have tried or have some ideas about engine tuning using some devices(tuning box) It is plug n play, a device that when you connect to your engine sensors, it would work directly without configuring or remapping the ECU(car computer). When you feel that you don't like or need it or for some warranty purposes, just remove or put some adapter to be able to configure as using your stock engine parameters or just simple remove and put back all the sensor connectors in normal.
With this device, your engine will be efficiently tuned, gives more power @ around 20% increase, save fuel and many others.
Sa mga nakatry or has some ideas from friends using it, pro's and con's is worth discussing here
