Recently we were asked to tune a 2.0 tdi A3, as the customer felt it lacked a bit of umph.
First thing we did was an oil and filter change. Then we plugged our diagnistic system in and found that the air flow meter was faulty, so we fitted a new OEM spec one.
This in itself improved the car, but we then set about tuning it. Stock it was supposed to be 140bhp and 320nm.
We wrote a new map which should see 175bhp and 400nm. The difference was immediately noticeable, especially 50 to 70.. Another happy customer
