as far i know, there isn't any issue with it, all needs some gud installation from a gud workshop .......
my suggestion for baleno is
do install Landi Renzo Italian efi kit , adv, emu (both of same brand recommended by installer), and Lambda Control System This lambda system will protect ur car from back fire and provides isntant pick up , gud pick in hilly areas, gud millege, no worry of bad cng being filled in ur cng cylinder and car is not picking gud ...... all this will be removed wit this lambda control system .......
lambda conrol system is of 12-15k around .....
otherwise there is another solution ...........
OMEGAS kits of Landi renzo , LOGAS efi kits, these kits are expensive like 80k around, but they are specially made for Efi cars, and they performs like hell ...... no difference b/w petrol and cng ........ else for more details , contact members here in pakwheels named , Logas and kkool for lhr and isb region respectively ...... they will help u out with latest technologies .......
