Dragon 700 Wide Open Issue

Boondocker kit with attitude 3.25 box, non intercooled and silber oil pump. sled runs great except full throttle. When i punch it i get a perfect 11.5:1 AFR then after a second or two it will go lean like 14.5:1 then back rich. any idea what would be causing this? TIA

Is the rpm the same or is the rpms climbing up as you are getting theses readings ?
I've never realy liked the afr gauges I have used . Jumping around all the time never consistent like yours .
Have you played with the controller ? How rich is it at wot long pull .
