It means you hit +15 PSI of boost pressure.

Thanks, but is that necessarily bad? The gauge will flash when that happens and Isnt always when Im at wide open throttle.

Should be fine, only time i would worry is if it never hit it (boost leak), or it went past it (over boost). The flash is just an indicator just like the redline glow.

It's also relative to your local ambient atmospheric pressure: +15 psi is less important at sea level (14.7 psi = 102% increase) than in Denver (12.1 psi = 124% increase).
