New heads/cam ... part of the cat was glowing red ever so slightly... rich? lean?

I'm also getting what feels to be cam surge below 2000... not sure if the two things are related.. Any ideas? The is TONS of power... just a bit of cam surge and this very faintly glowing cat... Btw the way, cat is brand new, so it's not clogged.

i know what a/f ratio is. I'm seeing rich and lean... . Currently i'm looking at the Histogram in datamaster, and depeneding on if i look at left LTerm or left STerm ... THe data changes Seems to maybe be running rich on one side and lean on the other???

There are people on the board that can read the file better than me.
Maybe someone will chime in and take a look.

What's your guess? Rich or lean? I'm guessing rich since it started glowing while idling plus it smells kind of rich

Only thing i've done is changed injector constant for 30lb'ers and messed with timing. Hopefully i'm just rich...

Re: New heads/cam ... part of the cat was glowing red ever so slightly... rich? lean?

so i got home today to try to fix my problem... I found both my oxygen sensors were loose.. Most likely the cause of my problems here i would guess right? At least the glowing cat should go away i presume.
