Ive ran across this too, and has to do with hooking stock hoses back up proper and using the original restrictor. If you get the two hoses backwards, you only get wastegate pressure which is about 8 psi. Give or take.

Do a search. Someone put up some good directions on how to hook it back up to stock. Good luck.

Sounds like its just running off the wategate setting.Maybe the factory ebc is screwed up.

Check the restrictor in the hose from the wastegate to the intake...if it's missing you never boost higher to 10 psi...i resolve the problem when i purchase a new hose with the correct restrictor on...

i think i am having the same problem is you. i put a mbc on a stock 05 wrx and then took it off and put it back to stock and now i cant boost past 10 psi. do you sugest that i look into that restrictor inside that hose? where is that hose located?
