The smoke test was done @ BMW but their machine only does 7 psi.... no results. I am trying to find a 3 psi loss... I normally push 17.5 psi and I'm around 15 right now. There may be an issue with my tune. Terry is working with me, but I've replaced nearly everything else and tested everything. This is what Terry is asking me to measure, I need to locate the vacuum line from the boost solenoid.... I cannot (with certainty) locate it.... this blows (pun intended). No dyno until I resolve this.
