Guys sorry for the delay cudn't install the device due to busy schedule, neways its installed yesterday and result is quite satisfactory, on the first test run it gave an average of 24.5 km/ltr and the way i drive was too aggressive
just for the stress testing, i m sure if i drive the car like i normally do (with light pedal) it will give mileage around 28kms. well if we talk bout performance i must say its 25% dropped plus car takes a bit longer self to start with a soft pedal unlike petrol car where u just crank without touching pedal. pics uploading soon car needs to be tuned again and the local pipe installed will be replaced by imported for better fitting.
For all those who said its a scam and crap, i would like to invite them for checking the device and also test it, its really a nice thing far better than cng/lpg.
