serious boost fall off!!!!

I just got my 05 back from a regular service and now it seems that at 6k the boost falls further down to 10psi it never use to do this before. The car is completly stock except for a hallman set at 20psi. i know that there are alot of gurus out there so if you can give mee some input it would help out alot

If you installed the controller yourself, check all of your hoses again and make sure the stock solenoid is capped off. Did you have 20 psi before the service?

MBC with taper?? I thought that the whole purpose of the MBC was to eliminate that/as well as give you control of boost settings.
