Default fuel cut?

2005 wrx catless up and down pipe stage 2 tune via cobb ap. Running fine wasn't hitting target boost adjusted actuator arm slightly hit boost at 16.3 So all was good, and been running great for 3 months. Today while in first gear, punched throttle to floor it felt like I hit a wall car just stalled Out when it hit 5k l did it three times same result. In the other gears it starts to get near 5 k you can feel it bog down. Car has 98k on it. Is this a simple fuel pump issue?

Second car shows no leaks of oil, checked it the other day it was 2 qts low. So I filled it up, and now smoke is coming out around dp right by turbo. I think that's where the oil is being eaten? Any help would be great. I know the turbo has a seal if it's bad cam it eat oil a lot? or any ideas on this? If I remember correctly the seal isn't replaceable right? So new turbo would be needed? Also no cel lights at all. I only have web via my phone so it's a pain to search for stuff I'm in ogden any help or advice please let me know or call text lol you guys have been awesome I thank you in advance 801-668-4176

I had a similar issue with my wagon. The general consensus is to leave the actuator alone as far as boost control goes. I would suggest setting the arm back to stock and perhaps try flashing the Cobb high wastegate stage 2 map until you can afford a custom tune. Like I said. The only really appropriate way to adjust boost is in the tune. Messing with the arm is essentially just going to force an over boost situation in turn potentially causing fuel cut. Anyway, if you DO get a custom tune and the problem persists, there may be other underlying mechanical issues to address. Boost leak, bad BCS etc.
