first of all Heres my setup, starting from:
Equal length exhaust manifold
Garrett t3/t4 stage 3
internal wastegate
2.5" IC piping
same side inlet/outlet front mount 9x24x4
HKS ssqv
FCD
Walbro 225lph hp fuel pump
12:1 FMU

I think thats about it...now I've read all the searches I could I sent emails to various 2gnt members and I've ask Paul....the car runs great until it gets to about 4000 and then starts cutting. I've never gotten it over 4000 and I've hit boost when I was tryng to tune the FCD. i've checked all the wires for correct patterns. I've checked all fuel lines for correct feed and return and vaccum to the FMU everything is hooked up correctly as far as I know. and yet I still dont get past 4000. whats the deal...damn it??? anybody please help me....I'm desperate!!!

You say youve checked your fuel lines, but whats your fuel filter look like? I ask because I had the same problem and it ended up being the filter clogged up too much.

We've concluded that the cause of his problems is his disconnected front O2 sensor.
