I logged a short run just a while ago. My AFR seems to be a little lean. Will you guys look at it and let me know what you think?
I added my current tune.

Your afr is fine, for N/A you want between 12.5 at 13.0. there was some detonation at frame 390. I would take your timing down 2 degrees.

Ian,
Do you know why my TPS % maxes at 84% instead of 88%? I had the floor mat out of the car for that run just to see if it made a difference. It didn't.

That is normal some read 88 and some read 84.
