``I just broke 1000 miles today and had the Cobb SF w /air box installed along with Invidia Q300 catback and Process West TMIC. My question is this, on the cobb website it states that target boost is 17.5PSI +/-1.5~ i was data logging and my boost hit 18.4, is that too high? when I went to targeted boost and logged it said 27+ PSI:(. Why is my target boost so high? I'm afraid of overboosting / hurting my engine I'm researching this topic as we speak on Cobb but if anyone has any knowledge on the matter please let me know.

Thanks,
Chris-

18.4 = 17.5+.9

.9 < 1.5

You're fine.

As for target boost, it could be referring to manifold + atmospheric pressure, where when you're reading boost, you're reading the MAP sensor.
