Well to start this I will say that I know that I need to get a wideband 02, and that the narrow band is not accurate. Now that, that is out of the way.....

What are you guys with LT's seeing for your narrow band? I was seeing around 890-910 or so before I put in my LT's and HF cats. Now I am seeing 955-965, and when I lean it out a little I get 1 deg of knock at about 4k. If I add .5 to the PE the 02 #'s stay about the same but the knock is gone.

I am not looking to get a tune that gets every single hp out of the motor, just want something close in the ball park that will hold me over until a wide band can be bought.

TIA

I see anywhere from .880-.970 with a flat 11.8:1 afr in my gtp

There really is no set number & it can vary from car to car & day to day.

NB usually in the 800s for 12.8-13.2.

Thanks guys. I have heard what dynocar posted before, but never saw what you posted foff. Seeing that now makes me feel a little better and not thinking something is messed up. I am just going to add that little bit of fuel back and keep it there at 0 knock until I can get a WB02.

Thanks again fellas
