Question My AFRs are not smooth

So, I dont have a way to log AFR as of yet, but what I can tell through my wideband gauge,
is my afrs start at 14.7, then by like 5000RPM its 11.2 then by 6500rpm it goes to 11.8,
why is this happening and my fuel table is totally smooth (ie from 14.7 to 11.4 at redline)?

That seems very normal.

Your car goes into open loop by 5000rpm most probably. The table does not represent what you will see on the gauge. It can be close depending on who tuned it, but it is not an actual representation of what will be displayed. 11.2 by 5k during WOT and 11.8 by redline is perfectly normal.

Perfectly normal when the fuel pressure isn't right.
