ERROR< DANGER!!! lolIf I remember right the yellow blue mode is the setting for the sensitivity on the yellow mode. maybe the fact if you have slow throttle movement you get into boost ok, but on a quicker throttle movement it falls on its face try to adjust the yellow blue up 1 (Raising the number makes it less sensitive) so your yellow mode can work correctly
the yellow blue is the yellow lower switch point, meaning, WHEN yellow comes on, higher means it comes in later and will have a smaller zone, lower means yellow is a broader zone.
