Hey guys,
well, with my disco light narrow band, at wot, i'm still 1-3 bars into rich with 2.7 on hitting ~7 psi. Now, i'm looking at getting an aem wideband 02, so i can see where its at, and then stick on the 2.6 and make sure its not going lean at all.
I know theres a couple of guys with them on with these pullies. What kind of numbers are u seeing, so in short, should i even be worried about starting to run less then rich to stoich at wot (cavs always seem to run rich) with the gm flash, s/c 310 injectors etc.
Thanks.
Nate

With the 2.6 im runnin mid to high 11s.......But I'm also not using the reflash so that should make a difference...
I'm not sure on the 2.7 cause I haven't put it back on since installing the wideband...

Nate, you should become friends with someone with a tech scanner. Adam has the snap-on one at his shop and man is that thing fun to hook up and have someone monitor while your driving. very accurate and gives you a real time view of what your engine is running. i'm sure if you asked him real nice he'd be happy to help you out. we did that when we put my charger in so we could see exactly what things were doing.
My A/F ratio is never stable. At WOT with the 2.7" it starts at around 12.5 and then slowly goes higher.
I'm running the embree 2.6 pulley with meth/water injection,thats the cooling mist set-up and at WOT with a adjustable FPR I'm at around 12.5.

No tech scanner will tell you accurate A/F ratio's under WOT conditions. For that you need a wideband, there's no substitution for it.

i've got coolmist m4 injector in. What kind of psi do u see with the 2.6. No other fuel mods? What do you have ur fpr set at? And are you using a wideband 02, if so, which one?
