Default Boost issues (serious)


1999 JDM STI
120K EJ207
(Boost gauge is MPA, not psi)

When I'm boosting hard and going through the gears just having fun my gauge reads max boost around
.1mpa which has been normal since the bought my car, and stays at that until I let go of gas obviously. Recently when I hit 5th gear it shoots higher than .1 MPA than shoots down too .05mpa even when I'm still on the gas. Once it does that, my car doesn't go higher than .05mpa in any gear and feel so much slower than normal. The turbo spool isn't as loud as it normally is either. Sometimes the problem fixes itself when I restart my car sometimes doesn't.

Maybe a boost leak. Should check the hoses
They become brittle.
