my stumble is from lean mixture? What do I do?

[bias]

I got my wideband installed and now I can see what's going on. For anyone that doesn't have wideband, Get it! The stumbles that happened before now I see it's from being lean between shifts. When cruising A/f is around 14 When I shift it goes to 17 and then richens back up causing the car to stumble? At full throttle it's at aboout 10.2 but it seems to miss a little. I'm at 15degrees should I retard more for 14pounds of boost? I have t28bb, front mount, q45 fuel pump, 450cc injectors, z32 maf, and eprom for tune. I don't have fuel regulator yet could that be the problem?

What wideband do you have?

Uh, just throwing stuff out there but if you had a recirculated bov you could vent it to the atmosphere. That would almost certainly make you run richer between shifts. It may not be the proper way to fix it, but it would be a way to fix it. It would be free too.

My bov does vent to the atmoshpere. If vthe bov spring is too strong would the extra air in the piping make it lean instead of rich?

from what I have learned.........

ideally

idle 14.7WOT 12.9ish

then agian Im a little new to this whole AFR thing. Im still running a tad lean at 15.2 at idle....... pretty sure it is a result of dirty injectors.

If thats the case then I'm way off. I guess it's time for a piggy back and some dyno time.
