Here is a pull at 10psi. After 4700rpm you see the boost controller is trying to take over so that's the reason it looks crazy. It was ready to take off like a rocket. More pulls Monday and I fly out of town so I will get updates Still unsure about the stock 6l90 we know it's going to go but when..... Spent lots of hrs tuning it but still stock and surprised it's held so far.
10psi 741rwhp 847rwtq @ 4700rpm SAE

Should be a beast! Once we get done tuning I plan to off these CNC Ported 4 bolt LS7 heads and stock ls7 intake and unported throttle body. Figure I would prove the heads first lol.
I have a Beck intake that sits nice but it's Cathedral port. So I'm thinking MAST big bore heads and the Beck.
Looks pretty on it.
