Has anyone fitted a Unichip PnP in a TS - Toyota Yaris Forums

It is quite more powerful. I wanted more acceleration. But according to my dyno tests, I have got torque and power throughout the entire rpm range, take off is much quicker now and also top end!
It is not a DC Sports header. It was manufactured by Viper Exhaust (www.viperperformance.co.za)

I also wanted to put a k&n filter but I decided not to, since it only gives you that extra 4kw at full throttle (accelerator completely down), the rest of the time, it will not perform as good as the normal intake system. I enquired about it when fitting my exhaust at the auto clinic next door, they told me they even had to remove it and put the standard intake system back on from one vehicle because the fuel consumption was very high and was not performing well at all.

They suggested that I should modify the existing airbox and run a pipe from the airbox to the bottom of the grill (for cold air).
