Like stated just looking for feedback on my 1st e85 pull. Car pulls good at 24 psi but i'm thinking I can increase the timing a bit to make more power. Thanks for the help in advance.

Just took a quick look. I have only tuned two cars on E85 but looking at your timing, the car may benefit from a few more degrees.
Proceed with caution.

As for AFR,

5k on up lines up pretty good.
3.7k to 5 K you are pretty lean. I would suggest getting that in order to match commanded.
During spool up you are pretty rich. That could be corrected with some mid range tuning using ecmlinks closed loop tool or you can adjust them based off your wide open throttle pulls.
