I have been offered a KO3 sport turbo at a good price. I'm assuming that this is a direct swap for my KO3 that I have on my 150bhp A3. I'm a mechanic so I can fit it myself, but would the car be drivable without a remap, or would the ECU complain? I'm planning to get the map sorted, but obviously I need to drive the car to wherever I choose to get it chipped. Also, is this a worthy swap. How much extra would I get over a remaped standard turbo engine? Thanks.
