I just installed a T3/T4 turbo on my 93 B16A2 civic and when I hit about 5 lbs of boost the car cuts out like I have a rev limiter.when I let off the gas it blows off and I can excelarate again.  Any thoughts? Also what fuel pressure should I be running for about 8 lbs of boost?

HAVING A SIMILAR ONE, I HAVE A B16A2 T3/T4 TURBO DEL SOL AND JUST LIKE YOU WHEN I HIT ABOUT 7LBS OF BOOST AND AROUND 5400/5500 (VTEC ENGAGEMENT) I GET THE SAME THING SIMILAR TO A FUEL CUT BUT IT WONT LET OFF EVEN IF I LET OF THE GAS UNTIL  I CHANGE UP, RUNNING STOCK INJECTORS BUT 450CC DSM ONES AND WALBRO PUMP ARE ON THE WAY,APEXI NEO INSTALLED.. YEAH YOU GUESSED IT I'M DOING THE OLD 'HACK'.
