my 2000 aristo v300 is stock. how can i improve the fuel economy?the fuel available here is 95ron only.in japan they claim 10-15mode 8.8km/l.i m not expecting this kind of consumption, but at least 14l/100km.please tell me what i have to do.the only thing i will add in the future is cat back exhaust and panel air filter.please dont tell me its impossible to have this consumption. i know a guy with 850hp on the engine and he is having around 11-12l/100km highway doing 160km/h!!!
maybe there is an piggy back computer that can be mapped to sort this matter. but i want one that doesnt delete the vvti function.
i know unichip is rubbish for our cars
thank you
