Phil's car will, quite easily, beat an OEM '09 STi.
(His tune, from ESP is Conservative, as well-More power is there, just add meth!)
Fwiw, Mustang Dynos read PAINFULLY low, but once you're "used" to it, it's really not that big a deal.
Dynos are a tuning tool, not a testosterone generator.
An OEM STi typically produces 225WHP, from what DSG and ESP have told me.
When modifying a car, figure $100 per HP over stock, & plan accordingly.
Phil's car is clean, straight, & more than worth what he's asking.
