My understanding is the ECU adjustment from driving in minor - you won't feel a big difference with that. My dealer told me to drive it hard for the first day or two but with a long busy highway drive home I really couldn't. I could instantly feel the difference as soon as I drove out of his parking lot and it was a big difference in the lower gears at lower revs!
If you can't feel a big difference in 1st and 2nd then perhaps something is not right with your tune. Have your dealer re-check it. Did it really take the stage 2 tune or is it still stage 1. You paid good money for this so best to be sure.
