i agree.....this is the most funniest thread ever i read on pakwheels..... hahahahahaha
secondly bhai, i think you should change the driver, or secodnly i think restricting the CNG supply is not a good thing to do with the engine. bcoz in anycase ur mad driver will still flore the pedal, then he is going to figure it out and increase the supply, if he does not figure out still he will floor the pedal and as cng supply is restricted so engine will suffer,
i guess the best option is to restrict the accelerator or to get the fourth and fifth gear out of the gearbox.
if none of the advises work which all pakwheelers have given, then the last option is below:
driver k Kaan k neeche zorr say Rapta karwao and tell him not to go above 60 in second gear and not to go above 80 in third.... and third should be the last gear to shift.....
