Hi this is my first wrx and I'm new to the turbo scene. I have experience with Honda and I do my own work on cars but I'm clueless when it comes to turbo My question is my 05 wrx is only boosting 10 psi at wot. The car currently is stock with a boost gauge only. I bought the car used and I think the previous owner had a tbe n cobb. Any input would be greatly appreciated. Thanks in advance. Car seems to be running great I'm going Yo do a compression test this weekend and a boost leak test. If the compression test comes out good would I need to do a cylinder leak test as well?

 

anybody?? i tried the ecu reset didnt work, ima try to swap out the bcs next and check my hoses.
