Q: I recently read that the 1999 audi A4 2.8 quattro is electronically limited to 130 mph. What would i buy to override this setting and where on the vehicle would i install the device?
A: It really goes 150-155mph. To do this, you need to replace the stuck ECU computer chip with a performance chip and you need to buy the programmer for the chip to program your engine and make it so that you don't have a limiter. This is very expensive to do. The reason they limited the car because it is unstable at those speeds.
