ok wtf?

[BOVADDICT]

Alright 95 tsi awd.

JUST REPLACED 2 DAYS AGO!!!
new turbo, new fmic, maft setup, new walbro 255 pump, new aeromotive afpr, new pte 680cc injectors, new crank sensor, new timing belt, new water pump, new thermostat, flushed radiator, crank walk tested(and its fine), compression tested (its fine).

Other mods, turbo xs mbc, ghetto test pipe with stock exhaust and a muffler, And thats all I can think of that would affect this problem..

SO.. my car sputters.. Since I bought it.. The other day it sputtered and then backfired a lot then boom! it blew up and I got a new crank sensor and all that crap. So today I got my car back.. And I go to boost and I hit 10psi and it sputters then takes off again.. WTF?!?!

Is this is aboost leak? If so it can only be the intake manifold right? Thats all thats after the maft...

Or is it my exhaust not functioning correctly? Hole in it? I DUNNO!?!?

Any input? Cause this honestly has been my only goal to fix this damn sputtering and its still here thousands of dollars later...
