2.0T BWA Power and Torque loss.

It will never adapt over and above the initial map upload and initial run. Fuel quality is critical on these for achieving numbers and keep timing pull to an absolute minimum

Do things ever adapt up? My car had a new lease of life months after it was mapped. The well respected place made a huge issue about different types of fuel and mentioned timing pull (new one on me but always happy to learn) a number of times.

Nope.  The engine is tuned for MBT (Mean Best Torque) at the factory which is then set as the base map.  It can't advance over that for obvious reasons.  The ECU will always try to protect the engine from over advancing and over fuelling.  I often read of some tuners adding more advance to the base map, but I do wonder how much of that is then pulled out again by the ECU.  It's not wise to exceed the timing VW set at the factory.

Anyway, I also experience inconsistencies with mine and I do wonder if it's fuel quality related.  I religiously use V Power but as it's the most expensive fuel at the pumps, I do wonder if it 'goes off' due to so few people buying it?
