For some reason recently when i'm in 3rd and 4th gear under heavy load and let off the gas kinda slowly instead of the DV going 'pshhhhhh' it flutters a bit. I've only noticed it under these circumstances though. Is that normal? Or is fluttering a sign of something not working right?

 

Fluttering aint cool. Usually a sign of a boost leak somewhere.

 

Dammit, i'll get it tested for boost leaks, if it is a leak .. I might blow my car up.

 

that sounds like a reason to use dynomite

 

Ok so i went to my mechanic, no boost leaks... Any other suggestions?

 

Get a boost gauge. Boost leaks can be hard to find, did he just vissualy inspect or use a boost leak tester of some sort? A boost gauge is a necessity with a turbo for diagnosing things like this.

EDIT:
Oh i see you have a boost gauge... What it read?

 

maybe instead of a DV...you installed a bird..and whenever you shift..it flaps its wings....??[8D].....yea..im not really sure...and if it turns out that this is the case....woah...sweet

lol yea it's a damn bird.. should have known. The boos seems to read pretty good. boosts up around 15 - 18 psi. I had him do a pressure test by the way. So there are def no leaks.... ?

 

Check the wires on the N75 valve and inspect your diverter valve.
