Your prediction may be right.
This morning I was driving to work and suddenly I thought that I could use some more grunt in 6th gear above 100kmh.

I was blowing everyone of the road, but still, I could have blown them in a more savige way

I will NOT do any more engine tuning though. maybe sport airfilter, but no millteks or intercoolers while my car is under warranty for the next couple of years. And then I probably switch to something else.
Suspension mod is a possibility, though. But not in the next month.
