I've been driving the car around on 12psi with the Infinity and a few small issues with the tune, but without really unlocking the full potential of the motor. So after a few failed attempts to get local tuners I decided to take it up to Empire performance and have Alpha tune it.
There aren't many decent dyno sheets with a VVT-i head, 6466, cast manifold and 8.5:1 compression and I originally thought I would be lucky to get over 700. I was completely wrong!
Motor
Carillo h-beam rods, CP pistons with .250 wall pins, bored .02, stock compression.
Head
HKS 264 cams, VVT-i, Supertech hardware, mild port and polish, leaking valve seals (lol)

6466 .81 , ported cast manifold, Tial 44mm gate with a 12psi spring.
Fuel System
Dual walbro 450, FID 2000cc injectors, all Teflon lines.
Pump gas
After a few boost leak issues and my mac valve shorting out !? He was able to control boost and did an initial run at 13psi, which was over 400whp. After that he was able to turn it up to 19/20psi on 93 and made 580whp, but decided to turn it down to 18psi.
E98
This is where it got really fun - He turned the boost up to 33psi
This was the final number - He decided to pull out some timing and lower the torque
Here's a video
