Is the manifold and exhaust system standard?
Mine would drop into limp mode when I had hole in the flexi-joint.
The inrease in gas flow is seen by the MAF and mapped by the ECU software to be in error.

Just another thought, 17PSI is very close to the point where the MAP sensor may come ito play, so a spike into and beyond is another possibility.
