Not sure what is causing that but whatever it is likely causes the boost to fall below target as well.
I wonder if your issue is a dirty/faulty MAF. Does the car have aftermarket filters as I know the oil types can cause issues with the MAFs.
This log is from my car although it's the stage 1 93 OTS it should give you a reference point to help look for odd patterns in your own.
