getting less than 10psi.
Motor and turbo are new with less than 15k on either one. Any guesses on what to look for? Also, is a 2008

tried the search function, but couldn't find an answer...quotes don't seem to work too
weed out 100's of hits.

Thanks,

Any CELs ?

If not, I would check all the turbo piping for any loose connections. Also check the intercooler for evidence of cracks in the end tanks.
Next step if nothing is found visually, would be a leak test.

 

No cel's... Another member is sending me another spring for the bpv. Going to try that, he also suggested it could be the cold air here too... I'm in Wisconsin.

boost was never real well in the summer either though. If this spring don't work, and I can't see anything, I'll wait till spring to find someone to do the leak down test.

 

auto or manual?

 

Ever get this figured out? I had a similar issue that turned out to be a cracked intake pipe from the intercooler to the engine. The crack was along the seam and not visible unless pressurized.
