I had one go through my shop once, but I have never used one myself.    
The guys I've talked to that have used it say that it is deadly 
accurate.   +/- 0.1psi at all times.   If you set it to 14.9psi, it stays 
at 14.9psi, exactly.   It takes about 4 or 5 acceleration runs to "learn" 
your engine's frequency response curves, but after that, it nails your 
boost set point.    Its very nicely made too BTW.    The wastegate 
frequency valve is huge.
