I just had my wideband installed today and my afr ratio is all over the place. At idle it flutters between 14.7-15.1 but when I am driving its looks like my wideband is playing ping pong with itself. I am on a stage 2 tune with intake, and full exhaust with a highflow cat. Is it the mods thats messing it up or is this just normal for a stage 2 tune? Also it is about 10 degrees here and in the negatives with wind chill. I know that can effect it. Any help is appreciated.

its normal for it to be jumping around while driving, it flutters between 14.7-15.1 for emmissions purposes i believe, ur will also notice it will richen up while you shift then go up while cruising, prolly drop bellow 11 when WOT..so ur fine..

That is normal. It is called "switching" and is the O2 sensor constantly switching Mv's

You should get tuned though because the gm stage 2 afr is off at wide open throttle. They run extremely rich, as you will be able to soon when you mash the gas. Your afr should be around mid to high 11s however GM has you closer to mid 10s which is horrible. You can also pick up a good amount of power with a custom tune and better drive ability.

Numbers sound completely normal to me. My GM2 Tune was dead rich peggin 10 at WOT.
Get a tune to get your maf/ve/afr dialed in.
