trouble at 4500rpm....

my car begins to stutter at about the 4500rpm mark, now thats the transition from primamry to secondary turbo so I'm thinkin theres a problem there. But tonight I went for a drive and managed to get it up to about 140kmh in 4th and I get a fuel cut??? so now I'm thinking its a fuel problem. maybe not enough fuel under high boost?? I'm running PFC so now I'm thinking why am I thinking at all? shouldnt the PFC take care of this bit?
