Default Fuel Cell shows 15 always..instead of 22.....wtf?

Up till now I have seen fuel cell at 15 on occasion at WOT...typically during a shift. Made a run this evening to just check things out and made a bunch of WOT bursts... came back to look it over and see mostly 15's....and only a few showing 22. This is a first....any idea why the pcm would do this? Car runs strong and shows no codes.
Thanks for the input.

My truck is the same way. It does it with stock tuning, HPP3 tune, and my Magnacharger tune.

Very weird. In between shifts, depending how fast you are, you'll get fuel-cell trims 15/13/21 etc.

I sometimes get cell 22 while cruising in 5th or 6th. ( I believe it must be the PCM going through a learning cycle or something like that)
