Then you "T"d it into the the correct line. What supercharged cars have you been around that make a happy median at 8psi?
All of these cars tend to be a little different...like stated...most of them range anywhere from 5-7psi bone stock...your factory boost gauge is worthless...and your real gauge is accurate. If you installed headers I'm sure it would possibly even drop. That is why people toss on smaller supercharger pulleys after flow mods...to get the boost back they "lost" due to a freer flowing motor.
