Thanks! The avg consumption of the LCI/facelift version (which includes the Efficient Dynamics technology ) is about 0.9l/100 km less than the 2005 version. This could explain some of it, but I have to admit that I had to try quite hard to reach those figures. It is indeed much easier to increase it by 50%..;-)
Difficult to say about the actual difference... I do think the throttle response is somewhat better now (and it wasn't so bad before, either...), which also is claimed in the product description: improved "Leistungsbereitschaft" as the germans so elegantly put it :-). However, of course it's the sound change of the intake and exhaust combined that is the big thing!!!
