Will the A/F ratio be leaner if taking reading with wideband after "HOT" cats (probe clamped inside exhast tip). My full throttle A/F ratio is 14.1

I have included a before and after nitrous run. See below

If I remove cats and use test pipes. How much richer will A/F ratio reading be ?

There are alot of opinions on this right now... I think it's best to get the WBO2 before the cats, others don't.

I think you are in a good posisiton to make back to back runs, one with cats, one with out cats, and let us all know.

Then again, someone else may have already done this and want to share their results

Thanks. But it might be a couple more months before I can get back with info.
