just reinstalled turbos and car won't boost

help me troubleshoot this guys, me and Lost Time have been working on it, but i'm lost...

i replaced the turbos, so that means i removed y-pipe, turbos, etc...you know the drill

i put everything back and put the fluids in, got down the street, can't surpass 0psi...it just bogs, its like limp mode without the check engine light...i'm checking all of my vaccum lines and trying to determine if they're routed correctly, any other ideas? help? suggestions?

so far i have checked/verified:

boost map sensor, CRV, BOV, CRactuator...

help?!

So it's running reasonably well after the shirt incident? GOOD for you! Felt bad about the ration of S**T you had to take there...

yes, and i found my boost leak...didn't have any pills in the lines, so i was able to hit 10psi several times before my check engine light came on

didn't get any error codes though, i'm thinking maybe the oil level was low or something stupid like that

did you see my before/after pics of the turbos? i'm glad i screwed the old ones...they were shot anyways, and I got to fix a lot of things in this whole ordeal

Yeah, those pics were a hoot!

I had my check engine light coming on during freeway cruising when I was running injector cleaner through the system. Never stored a code, and once I got back to regular fuel (i.e. 92 octane), no more CEL (or MIL to be accurate!). So who knows?

Glad you're up and running!

yeah, i'm proud of the turbos i put on...they were brand new looking, i think i want a powerFC ECU now, with the commander

wouldn't that give me full text check engine lights ?

i'm sick of diagnosing codes and having a vague understanding of how the car is running

this time i ran NO air filters, and i also have fully opened exhaust on stock ECU, i felt it leaning out on full boost

would the powerFC fix that?

Well, I'm glad resetting the ecu that "last time" worked. See, I told you the worst that could happen is you waste 30secs of your life. The PFC doesn't throw any lights at you, not that I ever miss them. And I wouldn't run around too much under boost without any air filters. Next time you might suck in a low-flying bird or something.

used panty hose this time...works awesome

your CRV (bov really..) made all the difference in the world, just have one problem now...

after about 30mins of driving, it will bog around boost and then check engine light will come on

if i go under the hood, and remove a hose from the visible pressure tank, it makes a Pshhh noise and then the car works great.....

any ideas?
