JB4 psi variations...

All I'm running is JB4 map 5, DCI, and 93 octane on my e90. When I first installed the JB4 after 3 WOT pulls, I was getting ~14-15 psi WOT pretty consistently. Now a month later, it seems to top off around 11-12 psi.

Is this fairly normal variation? Should I expect it to climb back to 14 psi in colder (warmer?) weather? Or is this indicative of something amiss?
