so here it is. i did a boost leak test and found that one of those vaccuum hoses up by the tb was leaking and also my wastegate was leaking. replaced the wastegate, fixed that hose and was able to compress to 20psi (where as before i couldnt go above 5). from there it took about 32 seconds to leak down. now the car sputters horribly, wont go into boost, and has a loud fast ticking noise coming from up around the intake manifold. i also included a log from the few seconds i was driving. any ideas?

sorry to waste your guys time with my stupidity. i disconnected my maft when i took off my intake and well..um...didnt reconnect :(
 
I too have the same problem with a few exceptions. It doesn't stutter when idling but at about 3500+ rpm it stutter and then eventually dies. I've done a compression test and all cylinders check so no blown head gasket. I don't know what's up. I tend to think there is something wrong with my MAFT because the wideband afr readings are erratic w/ insane SAFC adjustment, no boost, car heats up quickly, and fuel pressure surges. I'm stump. Open to all solutions what may be cause these problem. Thanks.
