I should have known I wouldn't get a responce in the West forum. So here goes. I am getting a 8-5-10 boost pattern. I found one small leak in a hose, and I thought I fixed it but my pattern is still the same. I am hearing a louder whoosh coming from under the hood then I have ever noticed before.

The primary seems a little slower to spool up, and never reaches 10lbs. The needle on my boost gauge is not steady either, it is shaking. Boost drops to 5 at transition, then goes up to 10 when the secondary kicks in. This started about a week ago. Any ideas?

 

i heard that same noise and i found out that my twins were cracked.............my advise put it on a lift and check for oil around the turbos

 

Hmmmmm, that could be a possibility. I don't see any oil leaking though...
