New SBT engine - lower compression now?

New SBT 951 engine installed. Carbs redone. Dry compression at install was 125psi (my gauge reads low). After 5.5hrs at end of break-in per SBT proceedure now reads 120psi(MAG), 130psi(PTO). Premix used injection. Used about 1.5 tanks.
What's going on? Any ideas before I'm looking at another engine?
Happy 4th!
