Looking at my logs, I noticed my AFR Line is much more "wavy" on E85 vs 93.

Any Ideas about what could be the cause? Is this something to be concerned about?

My fuel system should be good, I am on stock turbo with 255/1250's

I have no other issues with the car,looks like its making good power, it has full bolt ons and i am running tephra 7 with 4 bar.

 

Looks like the tune needs to be fixed or smoothed out

 

You have a very choppy fuel map.
