Tuning STi's???
No problem man, you can find free maps on openecu.org.
Also, many people say that the VF39 (stock STi turbo) is not capable of running that much boost. Well, I used to run peak boost of 22psi with a taper to 18psi at redline on my WRX (not the STi). My buddy has managed to run his at 25psi of peak boost, this is on a turbo that runs a mere 14.5psi stock. Obviously, play at your own risk and remember that the turbo will be a bit stressed at those levels. Note: I don't know anything about the VF43 turbo on the 07s.
I wanted to add that my WRX made 265whp & 280wtq on a Mustang dyno in about 80 degrees of South Florida heat (outside). I made full boost by 4000rpms.
