I have a 95 Audi A4 1.8T with 60k original miles
Im thinking of fitting one of the above chips to my car but im wondering what sort of performance increase im going to see in bhp and torque.
Are these chips stable and will it cause strain or wear on the engine in long or short term?
Also, instead of making the 400 mile round trip to Kent and back is it possible to rip the ECU from another identical motor to mine and send that off by post to be chipped. And on receiving the new one what sort of garage would be able to refit and tune it for me or are they plug and drive.
