Dears I have khyber 99 limited edition..
The problem my car gives is that when road is little steep, its speed drops drasticallly i.e drops to 70 to 80 Kms on motorway..
Changed plugs etc (NGK) ,Tried several CNG, Petrol tunings but problem is still there ...
Is there any wayout of it, I need expert advice ?
Moved to CNG/Mechanical/Technical/Performance - MOD
