any car going uphill will consume more petrol. baleno shoul consume less than 1800 cc but then the question agan arises if you tune your car for cng it will definitely give a very bad performance on cng and viceversa..
your brake fluid has not been bled properly or of of your cylinders is leaking brake oil.
back fire.. its a common issue with balenos,but mind it, only balenos on CNG. sorry for being late as i was away.. read the firse10 pages of this thred and you will know how to avoid it in future.. also check the cam shaft sensor, it may be loose.
good to see that back fire problem is gone.
that 3 S is an idiot:S:-!.
Baleno is best tuned by computer.
Manual tuning always give problems in balenos..
