vaqas bro is running insane timings specifically for cng 
i timed my car back to original, loving the petrol drive. cng avg gone down but everythings much smoother, and who cares for the 4 days it is partially available.....!
my recent run to lhr via motorway -> avg. speed 140 (night drive), without ac. lasted for approx. 155kms. (bhera till peshawar road rwp)
my cng kit has gotten faulty, anyone know price of landi renzo's overhaul kit and price of complete cng pressure regulator?
