Default Chips in Ireland.

From the Irish news:
Young male Irish drivers, who are six times more likely to be involved in fatal accidents than any other category of driver, are creating further danger on the roads by over-riding safety and fuel efficiency equipment on cars.
And, many who have not notified their insurance company that they have over-ridden the original manufacturer's electronic controls on their cars could have their insurance invalidated after an accident. While third-party injuries would be covered, the car owner could be faced with huge medical bills for himself.
The manufacturer-installed chips keep the engine performance to 30 per cent to 40 per cent of the maximum in order to make the car more efficient and in order to ensure that the engine does not rev to its maximum and be damaged, or even blow up.
The black market chips remove the controls and allow the engine to run to their maximum speed. In a typical two-litre diesel turbo-charged engine, the new chip would increase the brake horsepower by 30 per cent from 170bhp to 230bhp.
It gives the car greatly increased acceleration from start and increases the top speed by 20 per cent. Again in a turbo diesel, this could increase the top speed of a car that was limited by the manufacturer to 130mph to around 160mph.

If a car with 170 HP were aerodynamically limited at a top speed of 130 MPH, a bump in power from 170 to 230 HP would only permit an increase in top speed by 10 percent, that is, 143 MPH, and this is assuming you don't run out of revs. The only way the 160 MPH scenario would be possible is if the electronic speed limiter caps max speed to 130 MPH but unlimited with the stock engine output would permit somewhere around 145 MPH. Then a further 35% power increase would allow a further 10% increase in top speed to 160 MPH. Again, as long as you've got the revs.
