Ever since i installed my fujita CAI i went from trapping 96/97 in the quarter to 92/93 so i guess i get to take it off and throw it away.
You likely have the filter too far up on the pipe. It blocks airflow... Also the actual boost level is dependant on several factors, including air temp, engine temp, etc. Unless you're running a MBC or EMS, the max boost observed will indeed vary.
