Re: low boost :(

had similar trouble with my wrx wagon i had to replace my rocker gasket and change plugs it now boosts at 1 bar must have been something to do with piping on the drivers side of the engine i also cleaned out all small pipe work with carb cleaner i think its a common with scoobs getting clogged up

Re: low boost :(

You've changed alot of parts and not mapped it fella, not really the right way to do it. Can cause all sorts of issues
