^^Congratulations!! Jon is a great tuner.. Your car should definately see low 120's in the 1/4.. just for reference for people that dont know how this dyno reads 485whp = 127mph traps in a 04-06 STI

It seems like the bolt-on 30R variants usually make about the same HP on pump gas as the rotated GT30R's do, it's when you add race gas/high boost that the rotated turbos really shine. For example my car on same dyno and 91oct made ~385whp @ 20psi, 110oct made ~460whp @ 25psi, and C16 made 497whp @ 28psi, and we still had more in it. You can see as the boost level raises between the bolt on's and rotated kits that the psi/hp gains begin to become more drastic.. Also i noticed between yours and my dyno graphs is that the rotated turbos seem to hold hp better at redline.

But anyways you made great power, im sure it feels like a rocket! When it feels like ur nuts go up into your chest you know u have a fast car congrats and enjoy the car! Hope you can make it to the 1/4 soon, i'd love to see some times out of this beast..
