Hello i have a 1998 eagle talon tsi FWD with a 6bolt swap and stock 14b turbo. some stuff on her is rigged a little but shes a work in progress and i bought her that way, only owned her for about 3 days now. When i bought the car i was told it was running at 15psi ( maxed the stock boost gauge out No problem) however when i hooked up a autometer gauge it was only reading at about 9psi max. When i drove her home she boosted fine and was very audible. Day 2 i got on her a little and on about the 4th pull i grabbed 1st then 2nd and on 3rd she fell on her nose and sputtered and wouldnt rev past 4k with boost. If i eased her and didnt build boost it was fine ( also only did this under a load and in neutral she was fine). Got home and was freaking out 
. Checked all the normal stuff, Shaft play, wastegate actuator was working, when i checked vacuum lines i found a line running from the Intake manifold to the back of the intake to a small sensor with a little nipple on it, looks like it should be bolted somewhere or onto something ( not with a hose just dangling on it) however since they were in the same area together and that hose wasnt hooked up i put it on the sensor. To my suprise i was able to boost to max and seemed to run fine until i gave her WOT, Then she sputtered and wouldnt go past whatever RPM it was at when it started sputtering. I am now not building boost as much or as fast. only around 6psi. What happened? Also might add that now i hear what sounds like air fluttering back out of the breather, The BOV is doing its job to some extent because thats still pretty audible. I am thinking maybe Boost leak? The only other thing i feel i should add is that i hooked up my A/F and says im running lean, never anything else just lean. I hooked it up correctly i think . I ran the wires to pin 76 on the ecu which is what the tutorial said. Im going to post some pictures and please if you see anything wrong say what you want about it not my any of my handy work. i just want my car to run right.
