View Full Version : Low Boost

I recently decatted and have been getting a steady 1.2bar for about a month now. Until a couple days ago that is.

I noticed I wasn't getting the same kind of pull at higher speeds and then realised I'm only making 0.7bar. The car pulls solid up to about 0.7 then seems to loose it's steam. It's as if tubby number 2 isn't coming on line - well at least it feels that way.

What is the first thing to check? Loose or split pipes? I'm a bit of a novice in the engine bay so don't know where to look. :search:

Also, if it was one of my tubbys would I be getting any smoke? I don't think I am. And wouldn't number one be more likely to go first? My cars done 106k so I guess both turbos are a bit worn.

Check the piping around the intercooler and all the boost pipes for splits which can be hard to find, failing that it may be a faulty IACV.

Good Luck, im sure its nothing major.
