Not sure where to put this in the forum...
anyways i have a 2005 subaru wrx with a 6 speed sti swap...
I just noticed a issue a few weeks ago and since then I been pretty busy so im just now getting to it..
my car is Not boosting at all well it seems like a true 4 banger right now...
it just has no turbo boost..
mods. Invidia catted downpipe. with a catless up pipe. SPT short ram intake, and a HKS carbon TI exhaust.
I flashed the ECU with ECUflash to stage 2. I do not have a boost gauge yet waiting till i get back to my home town. car ran fine after flashing for a few weeks and then i just noticed that i am not boosting at all.
I have thought that i was in limp mode and i very so could be i guess. I disconnected the negative of the batter over night and pluged it back i n and took it down the street and still no boost. so im unsure at this point what it could be.

Check your wastegate arm and make sure its connected to the wastegate actuator.

You either have a massive boost leak or a stuck/inoperative WG.
Since you disconnected the battery, if was a pissed off ECU you should have had boost back for a while until the ECU became pissed off again.
So your issue is a mechanical one.
Any CEL's, if so what are they?
