Vacuum/Boost Leak - Need HELP!

Hmm i'd be surprised if the Cans were bad (do you mean the cans on the turbo?)  If they were you normally should get a code (AJP? comfirm?) when the ECU command XX but only registers XX lbs.

if you mean the spider (the bypass valve / actuator)... a bunch of places  has a replacement unit for 35$  **BUT** i'd wager the Hoses are bad before the unit.  if you have a lift its super easy trace them and check them  or just ouright replace them for 15$ and then secure them with something more stout.

Still haven't figured it out and haven't found a leak anywhere.  IAT temps look normal I believe.  I got around to taking a datalog, and it looks like the boost is short of what is being commanded and the wastegate is always near 100% during full throttle.

I've replaced the boost control solenoid and inspected the vacuum lines and still having the same issue.  Checked the BOV's, cleaned the MAP and IAT sensors and also didn't fix anything.

Looking at my datalogs I'm mostly only seeing 4-11psi, with the car commanding 14.5psi of boost.  Very surprised I've not gotten a low boost code.

Wastegate % is 100 for almost my entire datalog when under full throttle. 

Still going to keep messing with it, but I'm pretty much out of ideas at this point.

FWIW check the wastegate Hose that leads from the Boost reference solenoid,which then feeds to the rear turbo actuator I believe! I don't have PICS @ the moment but might be worth while to inspect that particular hose in question!  Z

It's hard to imagine both actuators having an issue, but I would confirm that they are working properly, since there is no leak topside.

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

I've checked that hose as best as I could and didn't see any issues with it, but it is a hard one to see.  I followed the hose from the solenoid to the T-fitting that then split to each actuator.  Both appear ok from what I can see, but I did not remove them to inspect.  I did confirm they are connected to the actuators.

Right!  I'd be completely shocked that both actuators would go bad at the same time.

How do you confirm they are working properly?  Just see if you can reach them and move the arm freely?

yes, the linkages should move freely.  And the wastegate should actually full close and open.

I'll give it a try.  One on the back side looks like a pain in the butt to get to!

Thanks!

I know it's been awhile but I'm having the same issues with my vehicle. Did you ever figure out the issue?

I was betting on the WG orange gasket but it would be nice to hear back from this one.

Was the case for me. 2nd one too. But for some reason this one by the firewall was being tricky. It wasn't as obvious as the front when it blew.
