Thanks. So I had hooked up a ESS VT2 595 kit and had disconnected the upper radiator hose (not required, but did it for ease of mounting the bracket for super charger) and had not seated it correctly upon reinstall.

I pressurized it a bit and found the leak. I reseated the hose, refilled the system, bled it, and cycled the coolant. I repeated the test at 1.5BAR around 21 PSI. All is good now. Ill put my install experience and pics up soon.
