Default Arashi td05h 18g 8cm Dyno Results!!! (Every conceivable sup. mod)

Alright so I wanted a turbo that spooled quick, but gave a bit more punch and carried power a little further than stock. I had settled on a TD05H 18g with 8cm hot side. The thinking being the td05 would spool quickly and the 8cm would help carry the power into the higher RPMs. I made the decision to jump on one these Arashi turbos when ebay had a %15 off coupon. The turbo is an TD05H 18G 8cm. It was $719 shipped on eBay before the discount. Ebay capped the discount to $100 so I paid $619 shipped, then I get $30 back once I send an installed picture to Arashi. So in the end this turbo is $589 shipped BRAND NEW.

My car is a 2008 STi and the build includes the following:
Arashi TD05H 18g 8cm
Built Block
-CP 99.75mm Piston (SC7422)
-Skunk2 Alpha Series Forged H Beam Rods (306-12-1000)
-OEM Nitrated STi Crank
-King Race Bearings
TGV Deletes
ID1000 Injectors
Torque Solutions TMIC
AEM Intake
Perrin Inlet
CNT Equal Length Headers
Grimmspeed Uppipe
Unknown Catted DP and SPT Exhaust
COBB Acessport V3

I think that is everything. Once I got the block broken in I brought it to my local tuner, Baxley's Speed Shop in Windham Maine, who has a new MD-AWD-1100 Mustang Dyno. I let him work his magic and by the end of it she was putting down 336whp/336wtq at 21.5psi! I wanted low 300's on his Mustang, seeing how they generally read lower than most. I was very happy to see 336/336 and he was thoroughly impressed with the turbo. We are both curious to see how it holds up in the long run.

Here is the car on the Dyno and a graph print out:
And here is the turbo unboxing from a month ago:
