Got a strange thing happening, anything but WOT and i get 1 BAR, WOT and i get 0.9 BAR everytime. Have a dawes fitted as boost was erratic on solenoid but i'm now thinking there is a link between the two.

It really is a WOT issue, if you foot is only ever so slightly away from WOT it will pull 1 BAR to the redline, put it down that mm more and 0.9 BAR then lift up 1mm again and you get 1 BAR, i'm suspicious that the car may be leaning out but what diference does that last little bit of movement on the throttle make?? is the ECU changing timing or something for 100% throttle??

I've checked throttle pos sensor and all is good.

Any help or ideas would be a big help.
