Seeing changes in my part throttle afr's??

I just installed a cop and now for some reason my afr's are 11.9 to 12.1 at part throttle..I was gonna go wot ,but when I install little things like this which no one has ever mentioned that it would require a retune I play it safe and do p/t pulls..

Does afr's change when you go wot compared to p/t??If so I might have to have my tuner add a slash of fuel..Is there a reason that Im seeing this change from installing the new cop??

If I remember correctly I was tuned for 11.3 to 11.4 wot and before the cop install I was seeing mid to low 11's weird thing is I get no knock...
