Hey whats up guys im having a problem with my car.. it is tuned on aem v1 set to boost by speed for 15psi but i recently noticed it holds only 5psi trough all the gears at any speed was wondering what could b the problem any help is apriciated thanks ahead of time!

 

You have a boost leak somewhere. Check couplers, nuts(manifold, turbo, and wastegate) bolts, and vac. lines to start with.

 

yeah i checked all my vacum lines and the couplers i could see have to remove the bumper to see the rest but everything under the hood looks good

 

A boost leak detector is cheap and/or easy to make. It is absolutely essential to verifying there is no leak. Do it.
