I presume this means you have tested the WUR boost response fuel pressure function?
If so, that is not what I'm talking about. Your WUR is dumping fuel with no boost response function, upon hitting boost. The only thing I can think of at moment is that the fuel piston has been allowed to travel much further (not really big in mm terms - maybe 0.5-1mm) than it should to the air plate movement. About the only way I can think of this happening is the WUR pressure going 'soft' on you in response to a sudden airplate movement. This is different to testing the WUR boost signal effect to the pressure - it is comming at it from the reverse end so to speak when it is really supposed to be a one way effect.
If I have understood you right.
