when i was searching for a liana in 2013, i met few car dealers at main auto markets of karachi(jamshed road and khalid bin waleed road), spare parts people and mechanics..they all said never to buy a liana with injector wali cng kit..this works extremely perfect with a new car but once it starts to bother, the 3s people rips you off as they have monopoly of expertise in this kit.. i saw 5/6 cars with ff cng kit and the owners asked themselves that they will lessen the price for putting in the local cng kit for me...i met a major of army selling his white beauty and he said that he will lessen 14k for me for putting in the local cng kit..so, at that time i got an idea that the kit costs 14k in 2013..
my car too is ff cng, but its injectors wali kit is uninstalled and local landi renzo is in with emulator. Mashallah car has never ever bothered on cng..it runs much better on cng than on petrol..BUT...the cng avge is considerably lesser than the ff injector kit ..i heard people saying that they get 150km in twin cylinders in khi on ff kit but with local kit, you can get max 100-105km..
