T5 no boost
I've just purchased a 2004 s60 T5 and noticed when I was driving it felt quite low on boost so I decided to install a boost gauge which is telling me I’m only get maximum of 4psi. I’ve check the wastegate, hoses for leaks, bypassed the boost pressure sensor and still minimal boost. I’m new to these cars so it’s tickling my brain. Any help of advise would be greatly appreciated.
