With classical chip tuning the original ECU software from your Audi will be exported, modified and then imported. At the most cars this is possible via the OBD interface (OBD = On-Board Diagnostics). At other cars, it can be, that you must send us your ECU, that we can access directly to the chip.
Manufacturers produce their engines so that a large compatibility and flexibility is provided in all countries. The engine control is so programmed at the factory so that a car can be right with extremely different temperatures and climatic conditions, other environmental influences and different fuel qualities.
Consequently, an engine like from your 2.7 V6 381 PS (RS4) (ECU) including its control systems is often larger dimensioned and are supplied from the manufactor with power reserves provided in order to be fair in this range in every case. On the other hand, it is a simple question of cost for car development.
And at this very derelict power reserves we go with the map optimization Audi A4 (8D) and optimize e.g. fuel quantity, fuel injection together with the height of the charging pressure in dependence on the signals of the sensors for the air present composition, RPM, load and other correction factors to calculate the required injection time, etc.
Remove speed limiter
When your A4 (8D) has a speed limiter and you are interested on remove it, classic chip tuning is the best way to make this.
