That is the trouble with an electronic gauges, they will capture the briefest of spike. Even if it is too short (fractions of a second) to actually register on an analogue gauge. Providing that you are not seeing this register on your normal gauge, then don't worry about it .

However, if this is what your SECS is continuously seeing, then make sure that the hose hasn't popped off your actuator giving unlimited boost .

Build the boost progressively in a tall gear from low rpm and report back what it is climbing to and at what revs. If it starts to climb above 14psi - BACK OFF. Take it to your tuner for a thorough check over. I would also point out that some NMS ("Gunship") stage 1 conversions have been live-mapped to run this kind of boost in the mid-range, so it isn't always an issue, but I would get it checked out before you lunch an engine....
