I recently bent a rod in my trickflow headed 6.0 so i threw in a stock headed 5.3 in its place. I took the car out yesterday and was logging it and i noticed its got a nasty lean spike, from looking at the logs its a real sharp spike and the afr recovers the next frame which is in the same cell in the main ve table. Looking at the main ve table there isnt any major deformities or low spots in this area of the ve table. Now the car isnt tuned all the way but it is not off by far. Is this a VE issue or should I be looking else where?

*EDIT* This is a boosted COS3 With no maf and no PE
