You are adding fuel which the ECU does not know about (methanol injection), so you should expect the AFR to be richer than the ECU's low-det fuel map targets while the methanol injection kit is operating.

Do you work for Top Speed?

also the fuel maps are often not an exact match
to real afr readings..

if the map said 13.x your wideband might say 11.x.
