Hey guys ? this is not as stupid a question as it may sound Bought my S3 about 10 months ago and changed the MAF yesterday with awsome results. When I bought the car the guy said the car had been chipped by 'big boys toys' in London but didn't have a proof of this. Is there any way I can tell if the car has actually been chipped without having to fiddle with the ECU ? cheers, G.
