Asked by Steve G
I'M considering installing an aftermarket performance chip into my 2004 Toyota Prado 3.0-litre turbodiesel. The makers quote an extra 26kW and 53Nm above standard of 95kW and 345Nm. Are there any issues with these chips?

24 Apr 2008CARMAKERS tune their cars to suit the average motorist and they also leave a safety margin with their tuning so they can be confident they won't have problems once their cars go into production. Tuners can tune more precisely to achieve a desired outcome, be it more power, torque or fuel economy, and they can play within the manufacturer's safety margin. By some fine-tuning they can extract more power and torque than a manufacturer would dare do. That means you're running closer to the edge when you install a chip, but that doesn't mean you will have a problem. Your best course of action is to choose a chip maker with a long-established, good reputation for doing reliable work, and perhaps with some sort of warranty. Then ask to speak to other owners who have had the same chip fitted to their cars.
