The reason why I asked about a flash is that on the most recent one the dealership did on my truck really changed how the boost was made, normally at 1/2 to 2/3 throttle I was at 12 psi, now it is full throttle. Throw the tuner back on it and see if the strategy number is different. That and maybe throw a tune on it and see if you boost comes back. If you can hit 17-18psi then you do not have a leak. Yes you can pressurize from the intake. That isn't a problem. Just need to cap it off.
