loss of boost

Okay guys,
Normal boost numbers for me with the 275 and delete are about 15 to 19 at 80 mph. Yesterday I noticed that the whooshing sound I usually get when the torque converter locks up was not nearly as loud as usual and now my boost is only about 7 to 9 at 75 or 80 mph. Anyone know what could be going on? I haven't lost any coolant and just a quick visual noticed nothing out of the ordinary. I still can see 25 or 30 psi taking off without going WOT although I have seen 55 or so in the past.

Check your clamp coming off the bottom of the intercooler under the front bumber. Mine broke and came off.
