Can you really feel the difference with the P-Tronic and what re the fuel economy numbers in Km/l... do you know?!?

They (P-Tronic) say that it should go down about 15%... tahnk you!!!
The P-Tronic Box will take about 90/100 miles to really start to work, the ECU has to adapt to it, fuel economy will get better with miles, mine gives 29/30 MPG around short local runs, on the motorways and longer runs (20 mile+) it gives 32.8 MPG at the moment, I have covered 820 miles so far, I expect the economy to improve after 1200+ miles.
The performance is much better using the box. you will only see by how much when you take the box back off.
