There's no doubt you can install and tune them on the spot. But maybe after one or two days or even one week, the ECU will [/B]re-learn and compensate[/B] the whole Fuel Curve around whatever settings that has been adjusted using Piggyback. Yes it is still effective, but not as much as it would work on other model of cars. With Piggyback on 20V, you can only hope to adjust Fuel Map on Open Loop mode (80% - W.O Throttle), while in Closed Loop, any reading from the O2 Sensor will be used to compensate Fuel as required. So you see, it's not an easy thing to cheat 20V ECUs. EG9, if you feel that your 20V is not that responsive, it is quite possible that the Throttle Position Sensor and AFM setting is not set properly, my advise go and seek Sifu Accoustic and ask him to check your TPS and AFM, then belanja him makan besar laa. He tune my TPS ONE time onli and until today it's very satisfactory.Bottomline, if you need more power - save $$$ and go for Cams and Standalone ECU - the only real path to power.</blockquote>
