Ok so I'm new to tuning and thought I had my wot afr set. But I only set it in 1st gear, 02 m6 camaro, because I was on the street. So at the drag strip last weekend I run and noticed my afr going from 12.8 at WOT through 1st gear then once I got back to WOT after shifting the afr was 11.2 or 11.4 I can't remember. But it was low 11's. What could be causing this? I have no idea where to even start.

I don't have access to my tune right now because I'm at work but I will upload the tune and log of the run later today.
