Prado perfomance upgrade

Hard to be subjective about "low down performance" with an auto? Does it not shift down a gear soon enough, or what? The torque convertor should give you all the torque you need at low speed? If not, fit smaller tyres.

You can change the main muffler for a straight through type. Will increase the noise a bit though.

Check out www.lcool.org and there are links to a Yahoo group. There has been messages on there about performance improvements. Basically they are the muffler ($400 or less), a unichip ($1250+) or a supercharger($$$$$$). The later is the best, some will argue that the other two don't have any real noticable effect.

I own a 3.4 V6 Hilux, and changed the muffler. Its a bit noisy now, but it does go slightly better. The Hilux would be much different in the noise department than the Prado, as the Hilux has virtually no sound deadening.

I believe there are even extractors on the market now, but they are expensive to fit due to the tight confines of the engine bay.

I was going to get a unichip, but my lease is up in a year, so i don't think I will bother. Would be good to drive one with a unichip to see what its like though.

Supercharger is the way to go, brings it up to nearly the power of the new 4lt V6 Prado, but it would cost heaps, like $5k at least.
