So I just recently completed my engine swap to the redtop. It was pretty much fine except I was in the midst of troubleshooting boost flutter. This morning I took it for a test drive and the IC pipe coming out of the turbo popped off while going from 2nd to 3rd. (I didn't know at the time this is what had happened) But I was just a block away from my garage, so I idled back. Once it was in neutral the car died.

Since then I have

1. Tightened the piping back down.
2. Attempted to move the battery to the trunk(Attempted to crank the car twice), but it looks like the wire gauge was too small so I moved it back.
3. Corrected some of the ghetto wiring I had going to my TPS.
4. Finally put the belt on for my power steering.

I attempt to start the car again, and it starts up just fine, real quick, like as if it was a new car.
Idles at about 1.0-1.5 for about... 2-5 seconds
Then starts to misfire and ends up dead after about another 5-10 seconds.
When I push the throttle it will rev up, but it's also flaky.

I have the crankcase hose going into the pipe before the turbo, but the BOV goes into Atmosphere.

I tried disconnecting the MAF, and it's the same result except I can't rev up the engine. I tried to harden up the BOV, and it's the same thing.

I'm going to go double check my TPS wiring job after I post this.
