Lean spike free-reving

[AJ'S 88NA]

I just noticed a lean spike free-reving to around 4k rpm. Around 16AFR.
Under normal driving AFR's are normal around that RPM.
Maft-Pro SD/ LM-1 O-2.
Is there some other adjustment I'm missing?

i'm guessing it's on throttle tip-in. play around w/the response settings to eliminate it.
