Hi I'm new to the site and new to audi ownership.I recently bought a 98 plate audi A3 1.8t sport.the car has covered 105000 miles.very fun to drive and has been modified however I am not sure as to what extent as the previous owner hadn't had it long and was keeping as a back up to his seat ibiza fr.it has a very expensive exhaust system on it and the only other thing that stands out is the blow off valve,there was talk of a possible remap but nothing to prove it.how can I go about finding out what has been done as this car feels more than a 150bhp car.any suggestions would be welcome
