This is SCN, you knew you weren't going to get a straight answer 
It's pulling more air than it should, even if it was boosting ok it should still only do 160 odd g/sec as it's stock.
When my outlet hose was cracked it was still boosting okay-ish, but n75 was high, as you'd expect (you might still have some logs!)
'tis really odd, for sure..
Check the platic pipe that the MAP's fitted to

If your sure it is a boost leak, you can find it by disconnecting the intercooling hoses at the TB and charge pipe ends, capping off one end and pressurising the other via compressed air and listening for leaks. Without the engine running its much easier to find it. This worked for me.
