    Dont think you would need an advancer in an older non-EFi Cultus.

    If your car cannot go above 120km on petrol without A/C even, something else is wrong.

    When was the last time you did preventive service and maintenance ? Carb cleaning, plugs change, plug wires check (and change if necessary), dizzy cap clean, CNG kit service etc. ?

    Mind you however, I wouldnt really suggest going over 100-120km with 5 people to begin with. Thora khuda ka khauf karo.

    Got 07 Carby Cultus and it goes upto 105 to 110 (with AC) on CNG when fully loaded. Thats the way it is, either change ur car or live with it.

    and yes, I have seen these non-EFi Cultus(es) running really fast on highways but I ain't interested. Plz don't try it with 5 people on board. My observation; more loaded it is, more BRAKELESS it becomes.

    In my opinion cultus is supposed to be driven at 80-100max. With 4 ppl in it.
