Hi P-Wheelers

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

Thanks

Yeah first check its OE maintenance like fuel pump is giving full pressure,Lubes changed,All sensors etc working,Fuel ilter changed,throttle cleaned

Other than this you can go for after market Iridium,Platinuim Multi tips Spark Plugs and Air Intakes will make some diferernce.rest you can go for better fueling graphs wth SAFC or Maybe piggyback

Cheers

It really wouldn't make any difference chaning plugs or stuff like that.

My best bet is there is something wrong with the vehicle. Like wasay suggested, check the stuff he mentioned.

Best of luck.

wasay/Whisky i have had it thoroughly checked from toyota garden had all the lubes changed , got it tuned throgh engine diagnostics, one of reletibes also owns a 2.7 vvti 04 prado and he has the same complaint i.e underpowered. so guess this is a generic issue. thanks for the comments guys.

yeah 2.7 is a bit underpowered...if i were you i'd sell it and go for the 4.0l prado...just have a drive on that u'll know its awesome man.

4.0l one is limited edition and i think is quite expensive.. 3.4 wil be gud enuf..
