@aijanjua bhaijaan dont ruined your car with local cng mechanics try BRC on Main Shahre-faisal. They are almost twice expensive but the performance and mileage is good and BRC is also from ITALY. Trust me if u want to keep the car for like 2 or 3 years then go for BRC otherwise its your choice because i have a very bad experience on cng mechanics on Jail Road especially.
Aur haan bhai BRC guyz dont choke air-intakes which most of the cng mechanics do choking almost 60% to increase the race of car but when u convert the car on petrol its hell because of Air intake map sensor.
