s300 goes into fuel cut at 1.5 boost

I HAVE A CUSTOMERS CAR IN WITH A PROBLEM THAT I HAVE NOT SEEN BEFORE WHEN THE CAR GOES INTO BOOST 1 TO 1.5 PSI ,GOES INTO FUEL CUT
IN DATA LOG YOU CAN SEE INJECTORS SHUT DOWN
IF YOU REMOVE CHARGE TUBE OFF THROTTLE BODY AND RAMP UP, IT RUNS WITHOUT NO PROBLEM TO 8000 RPM AT WOT
ALL SAFETYS ARE OFF ...
