2013 vs 2014 F30 320d auto

What is nice about keeping logs is that you can always use the figures to compare and see when things change.
My 2014 F30 320d auto 8speed felt a little dull so i did a datalog just to see how it compared to the 2013 model i had.This was necessary because the last while i have been driving the faster BMW's and i thought possibly i had just forgotten what the performance should be.
What came out of the test is that the new car is indeed slower off the line and then claws it's way back to a higher exit speed over 800 and 1000mts.
So many variables could cause this.The slower pullaway due to less torque at low rpm is a symptom a larger turbo would give.Who knows?
The other variable is the diesel.In the old car i used 50ppm.At our Sasol garage you can only get 10ppm and that is what the new car had in.
