Bhai saab every car is same on CNG if taking about 1300cc and above, it depends on how well CNG kit is installed i.e whether installed with LC to improve pick and rpm drop reduction (specially in Honda) and depends on proper tunning too. Otherwise if you talk about suzuki guys then the thing I like is just their CNG fitting style i.e proper stand for cylinders etc etc. Heard from many liana users who are not staisfied with the performance of their cars. I recommed you for honda and install CNG kit with LC.
