Leaning out after AE kicks in, and when lifting throttle during cruise.
 

What am I missing? I have my AE dialed in pretty well. If I am sitting still and give the engine a rev, AE kicks in, my AFRs drop to around 12.1-12.5, but immediately go max lean before stabilizing after the RPMs drop back down. I've also noticed while cruising (low or high speeds), that if I let off the throttle slightly, my AFRs jump up and I hear the engine stumble. No, it isn't my overrun fuel cut. I have that delayed 2.0 seconds right now. This happens pretty quickly when just lightly coming off the throttle.

Anyone have advice? If you must have a data log, I can post one in a couple of hours when I head back home from work. If anyone happens to respond before then, what data should I log for a good view/result? Obviously AFR and VE. Any other big ones I should log?

Thanks in advance. This forum kicks all the ass.
I'm running:
MS2PNP
GM IAT sensor
AEM X series wideband
REAL RX8 injectors
no-name intake

I think it would help to see what your acceleration enrichment tables look like. It sounds like you might have negative AE values when it notices a negative change in map dot or tps dot

Tune and data log attached!

Go easy on me y'all. I'm a newb at this stuff.
