I found around 3500 miles the engine begins to open up (if you think youre used to it now, just wait- then you can spend your time between 3000-6500 rpm) and strangely after around 5000 miles the car seems to have more grip and it sticks better. I cant explain why that is but going over the exact same roads now the car doesnt skip over them- and all Ive done is drive it. How about that for modifications?! It improves automatically with time :-)
