Anyone have any pointers for tuning this turbo? Truck was well dialed in with the stock turbo & HP SOTF OS. On my dyno I am usually happy on stock air flow around 540-550 rwhp being conservative. Assuming now I have alot more airflow adding another 40-50 rwhp to the top tune shouldn't be a problem.

Jason,

I would run your desired boost near 53psia at sea level. If the truck is deleted you'll not need to make any adjustments to the vane settings from stock. If it's emissions on you can post the stock file and I can help you make some subtle vane adjustments to get it lit slightly quicker.
