My father has a 03 Prado 2.7 VVTi, which feels very very underpowered. I dont know how toyota have miscalculated the weight and powerwed it with a 2.7L engine. It feels really heavy while driving uphill and rather decelerates on Motorway when climbing the Kallar Kahar Range.
I was wondering if any performance parts or fine tunning can help. I know nothing about performance parts, so i need your help with:
A) are there any performance parts such as air intakes, performance plugs etc that can help
B) is replacing performance parts going to effect fuel consumption.
I will appriciate your opinions and suggestons
