Ok so tonight i was driving, not hard, but doing 120 or so, and the turbo quits boosting??? I was like wtf. it just jerks and sputters like it stalled but it didnt stall. so when i give it gas the turbo jerks and feels like a fuel cut. I check my a/f gauge and its running totally rich. The safc reads idle at 750rpms, but when i give it gas in idle to about 1100 it sputters and stalls out just as it would boost. U can still hear the blow off valve purge a lil when u gas it. but it sputters. What the funk did i do? did i blow my turbo? or did i mess something else up? any help would be greatly appreciated and soon!!!! thanks

vac leak?:shrug

what are your fuel pressure readings and egt readings? a digital air fuel gauge mean absolutely nothing.

Please check intercooler piping.

Start with checking the intercooler piping...
After that I'd suspect the MAP signal has been lost... You got an SAFC? Check the connections... if no SAFC then maybe you blew the MAP...

matter of time before he throws a cel 43.

blew off an intercooler pipe :thumbsup

You can blow off an intercooler pipe... from the boost. If you dont have all the pipes between the turbo, intercooler and intake on correctly then one can blow off...

Check each hose one ta a time starting at the turbo...

I would put my money on the MAP sensor. Look to that first. Do you have a missing link? If so, check the filter on it. On my missing link, if you were to cover the hole with your finger, my car woudl do exactly teh same thing.

Also make sure you didnt reset the SAFC settings, and make sure your "sensor type" is on the right setting. I fucked that up once to, and it did the same thing.
