Turn on gauge hijacking so you can see boost on the dash board (fuel gauge is my preferred position). With your mods, I'd expect to be hitting 15-16psi.
Ensure the car is warmed up, JB4 will target stock boost until up to a safe temperature. Mine take 5 or 6 miles to reach this temperature.. I have activated the flash hazards on warm up option.
