Hi guys,
Not to sure what's going on here, but today my car sounds like it has massive vacuum under the engine bay when I drive it and goes like an absolute slug. Checked my turbo's out and they are fine, so now I'm thinking I've got boost leak somewhere since my car was previously doing 16psi - 17psi and powering on yet now struggles to go any further than 10psi and my BOV does not sound like it normally does.
Could this be wastegate creep, any ideas or suggestions as to what I can do?
Thanks.

Problem solved one of the pipes on the car was loose Boosting fine just need to fix up the shuddering noise which I think is coming from the tail shaft.

I'm having a similar problem where I was going upwards of 14 psi but now can only reach 10 psi - won't go any higher, as if its maxed out! It still seems to have the power and acceleration on take off I normally had before the problem appeared except now it stops at around 10 psi and at that point I start to hear a fluttering sound, which I think is coming from the exhaust. I've checked all the vacuum lines and the accessible piping in the engine bay as well as the exhaust. Haven't had a chance to check the IC piping, will do it this weekend. I'm hoping that its only loose clamps, but what else could it be?

Ok just an update...

Waste gate stuck oPen , if not leaking clamps or pipes or vac lines . What type of boost controller ?
I'm running a Gizzmo MS-IBC. I've checked all the hosing. Removed them to inspect for any holes or tears. Couldn't find anything... Reclamped the hoses. Took it for a spin, same problem. So it doesn't seem to stem from the piping. I was leaning towards stuck wastegate as well, Borrowed an OBD to check for error codes - DTS 34 came up, which translates to "wastegate pressure too high". Is there any way to inspect/check to see is the wastegate/wastegate actuator arm is working without taking off the turbo's or a heap of other stuff on top of it?

Could be blocked cat as well . Drop exhaust In front of cat and take for a spinn.
Blocked cat is not an issue in my setup, but out of curiosity, can an exhaust leak (ie cracks in the dumps/exhaust or loosening of the bolts on the dumps) cause this type of problem?
