I have a small problem with the RB WS9.
Currently running the RB 6 plug with RB 25% on road fuel

The problem is that i can't set the LSN right.
If i go any ricjer than 1/8th it will drive very rich and has no power...if i lean it 1/8th it will act like high idle after letting the throttle from a hisg speed run.
HSN seems fine ...not lean or rich...makes good power.
