it's 38 Psi. if you are running 42 you might be running slightly rich but nothing that woudl affect you dramatically. you might be able to blow some sweet flames if you have straight piping from turbo back and bounce off hte rev limiter a few times.

i agree with Vutony. Be sure to set the FPR with the vacuum disconnected.
