are you in Karachi?, can you post the pics?
are you running on petrol?
I have the same model EXI PROS, you should change your tires, 4-2-1 exhaust and cold air intake, front lip spoiler and rear side skirts, upgrade your front brake disc pads with high performance one, change the spark plugs to platinum or IRIDIUM, change the wires/ upgrade battery.
and you are good to go with around 137 horses on your tap.
Do not induce force or else you will have to change the connecting rods, pistons, rings and possibly valves too.
D series engines are really sensitive, and if you fiddle with the engine it will broke down on you within 3-5 years.
I would recommend to go to jail road and plaza first, and especially visit optimum motor sports @zamzama
