    Because when O/D is off, car works in 3 gears only, which producing more power in enigne and getting more speed, but it reduce the GAS Milage.

    i m confused about your o/d problem because while o/d is off then my car goes till 125-130 and with o/d on it goes till 140-150 and in city driving average is 100kms/50 kg tank and 130-140kms if the speed is 110-120 constant

    Yes problem both on Petrol & CNG. i have discussed with many mechanics all told me that this is the maximum speed. nothing can be done more. only fuel injection can be increased but it will reduce the Fuel Average.

    same is the issue with my 99 vitz as well. Its petrol & auto transmission, and (whether o/d is off or on) it maximum goes upto 110. Got everything checked and pluds, oil, filters replaced. Still this problem persists.

    i haven't done anything extra to increase the performance even didn't got cat removed or throttle cleaning only regular maintenance done on time,i think it is totally based on the cng installer but in your case car is not doing well even on petrol so you should consult a good mechanic who knows vitz if you were in khi then i'd surely helped you out but same case my cousin ws facing in his platz then i told him to get throttle body clean and it solved his problem!

    And about o/d function let me make it clear tht if the light appears then it means that the o/d is off in this case the trnsmission doesnot shifts to 4th gear so the pick you get should be better but not the top speed and if o/d is on then all gears works smoothly and you get the top speed your car can produce!
