I guess the curse runs in the family then J/k.
On a serious note there's something really wrong with either the petrol pump you guys use, or your tuner, or your driving habits.
VTi Manual gives 7-8 if driven absolutely like trash - like above 4k rpm all the freakin time.
Another thing - guys at Honda Fort (Lahore) said that in normal city driving, VTi gives better fuel economy than an EXi. Member @UmarSattar can vouch for that since he was also present there.
