Kieth at
PURE TUNING worked his magic on my STi.
The Moore Performance Parts twinscroll setup is incredible and impressed us all with the power and response it allows. I want to give a huge shoutout to everyone who's been involved with this build, you know who you are.
Final numbers on 93 octane are 429whp and 377 ft lbs at 24psi, tapering to 19psi. The area under the curve is incredible, the way the power comes on and stays on impressed us all.
