Should be able to figure out with a boost leak tool and checking all the hoses and from/to TMIC/bpv today!

Can't wait to feel the car pull and reach target boost as it used to!

Fixed!!! Saw Mike and we quickly confirmed a leak. As soon as we took the tmic off, the culprit was found!

It was the hose between TB and TMIC!

. The inner lip had "lifted" creating a leak and causing the issues.

Hitting 15.5-16psi beak boost and no more "woosh" sounds!! Yeah to Mike & to an easy fix!

Congrats! Glad it was an easy fix. Too bad the dealership couldn't have taken the few minutes.

 
Many peeps had suggested this may be the problem, I just did not feel comfortable doing/troubleshooting it on my own!

I also agree that if the tech, at dealer, had actually taken the 10 minutes it takes (not even) to take the TMIC off, he would have spotted it. Not that I am defending him, but I maybe he doesn't work on that many GR's and certainly doesn't have the tuning experience. On the other hand, an argument could be made that the least he could have done as a tech is to inspect the hoses under the tmic, and not just check the visual hoses in the engine bay...

I will make sure to tell him of the issues as a FYI, not that it's gonna make any difference, and i'll TRY to not be an ass about it (I am feeling a bit frustrated/pissed).

here are 2 logs post fix. The car "feels" like normal and the boost target is within what I'd expect. I'm still not sure about the knock learning values and such, but I'll wait for other more knowledgeable peeps to chime in.

did you reset the ecu after the fix so the fuel trims/knock learning would be reset to 0?

that is my guess as to why it is knocking some. because it has been pulling fuel to compensate for the leak, but now that there isn't one, it's actually a little lean

 
No i didn't reset the ecu. I guess I could do that on my next fuel up (tomrrw).

I was thinking I would let it calibrate over time. I'm thinking that in the next fuel up or two, the numbers should be better.

 
you still want to reset it since the fuel trims are so high. It will take longer for it to learn backwards then to learn forwards, and you'll get a little bit more power and no knock

 
jojo, did I see you in Damariscotta at the carwash? I beeped and waved from the lifted green Forester.
