Hey guys, just finished building my a12 turbo and I am having troubles getting it to rev, it seems to idle well but as soon as the primary jet squirts fuel in it dies. It doesnt seem to be a fuel supply issue because fuel pressure stays on 4psi and the needle and seat are closing, I have also played with the float level and it made no difference

heres the details:

stock a12
t28bb turbo
blow through setup
surge tank with facet lift pump
vl fuel pump and malpassi rr reg
weber 32/36 carby has had rebuild kit and have added boost reference line into float bowl

Any help would be much appreciated
Thanks
