Default Boosting issues

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.

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?
