Im still going out for pointless drives all the time and I just find it very hard to drive slowly. I kept mine under 4k revs for the first 500 miles and then i started taking her up to 5k. now she is on 800 miles and i have started taking her up to 6k which she seems to like!

But as you said, it is very hard not to floor it! the noise it makes after 4k revs it just awesome!!
