Ignore narrow band readings?

Hey guys,

I've added a wideband to my WE4. I was getting a little bit of kr at 15psi (.5, 1.5). I added a wideband and afr's were at 11.5. Lowered the boost to 13psi. Hooked up my homemade boost leak tester and found leaks at the vacuum block (hoses and gasket). I replaced it with a billet block and a new gasket. I also removed the metal vac lines and replaced with all new hoses. No leaks so far. Now my afr at 13psi is 10.5 with no kr but the narrowband reads 780's at about 75mph. Seems a little low to me. It is a new denso unit. The old original sensor would read 600-low 700.

My question is should I stop driving myself nuts with the narrowband readings?
