Default AMS built and tuned 2.5l 2008 STI, 450+ whp on a 20g.. on a Mustang Dyno.. :O

Really really impressed with this car. Making 454whp on a 20g is pretty stout, but when you realize that this would be about 490whp on our Dynojet it becomes simply astonishing. And to top it off, it makes power faster than the stock turbo!
