Here is something to look at: I had a similar issue a couple years ago, it turned out the clamp on the hose leading to the first side intercooler had worked its way off the flange. The hose was still attached but let any boost over about 10psi just blow into the engine compartment. Check it out.

yeah thanks for the come back but i def check witch ever hoses i could .heres the quick history with my car i bought the car about 2 years ago n then did a boost gauge n found out my car was pushing only 10 to 11 psi n im hearing now that stock for a 225 is around 14 to 15 not sure but didnt think anything of it then i did the air intake cat back exhaust n forge 007 dv then finallt did the revo stage 1. but every time i disconectd my baterie or sumthing to that effect it would reset but then id get it reflashed and then it would go back to spike at 22 23 psi and holf 19psi but hte last time i got it reflashed it didnt work n i went back to him n he said i either have a bad dv or a boost leak so i just did the forge intake hose n the forge out take hose n my pcv set up that was caked in oil n whatever other hoses i could replace still no luck so im dropn it off to a mech to do a boost leak test tomorro but could it also be my airmass or n75 sorry for the long but short end of it i would really appreciate any feed back if possibly workn on a tight budget cant seem to keep replacing stuff thats not brocke thanks
