the manual you'll recieve actually gives you a few guide lines..
Namely the most impt points are
keep below 4000RPM
Don't race the engine
Don't Drive aggressively (not phrased this way)
Basically, you'll be experiencing what i'm experiencing now. Allowing Vans to overtake me off the traffic lights hahaha

break it in right, and it will treat you right down the road 
how far do i have to run it in for? 1500km? 1000 mile?
yeah actually i find it interesting subaru lists 1500km as the run in milage, while most other car manufacturers state 1000km
I believe the manual also states that you should vary your speed. Therefore, do not use the cruise control for the first 1000 miles. I was surprised that there was a "break-in" period because I thought most new car motors were broken-in before they hit the lot, but I was not thinking about the turbo break-in as mentioned above.
I actually just passed the 1K mark a week ago, so I'm finally seeing what this car really has. The brakes actually bite much harder now then when I walked off the lot. I did during that break in period climb close to redline a handfull of times, but hopefully that won't hurt me down the road. Of course this wasn't sustained redlining, just a quick rev and shifted out.

have you takin it to your dealer for an oil change? mine told me to come at 1000 for a free oil change...? im close 800+ so i was just wondering
well, since its free, why don't u just go back to the dealer/
I'm done! 1600km, or 1000 miles!

bah... Its not like hitting 5k will make it blow up. In fact there is a strong school of thought that you should run new engines hard such that it maximizes the pressure in the cylinder, therefore more effectively seating the rings. Motor Trend investigated and said it was "marginal at best" in producing more power from the engine over its life.

I know, I know. Most times when the RPM's went high it was because I was stopped on a hill and put to much gas to try to avoid rolling back. Actually, the hill-lock system has been great for me (a new MT driver).
Well, I don't really think that the break in is for the engine, more so for the Turbo, as they need to be properly broken and they do spin a lot faster then the engine RPM. I would caution do something other then the manual states.
I would agree that most cars come off the showroom floor not needing to be broken in, but it is much different with a turbo.
If you were to replace the turbo with a bigger, better one then you would have to do the same, keep RPMs below 4k for 1000 miles. It is so the turbo has proper break in.
