The final log seams to look a lot better. The spikes aren't so severe. I notice your TPS Threshold is 1.5v/s. This might be the problem you are having. You can see on your last log, your TP changes from 0-20% and AE is not even kicking on. I would try and get that value as low as I can without triggering unwanted AE. You do this by looking at the log and watching if the AE is kicking on randomly. The lower the value the more sensitive AE will come in. I hope this helps.

I had it set at .5 before those logs. In an attempt to swag something I bumped it up to 1.5. Either way did not help...however I am unsure if the problem was more severe at 1.5 than .5. I'll give it a shot tonight, thanks!

Well...I was able to drop it down all the way to .3. After doing so, I notice with every minute throttle movement the accel ativated. Sooo, up to .5 it went without any problems. After some more minor tweaking it seems to run better. I'm not gettin the lean spot nearly as much. I also changed my deccel from 80 up to 100 and it seemed to smooth things out as well. Now if I just knew of a reliable way to find which v/s I need to adjust (hint hint).

Anyways, I'm attaching my latest datalogs just incase someone can see anything that might need to be adressed.

For the v/s...with the engine OFF, look under tuning "realtime display". Watch the accel while stepping on the pedal. v/s is volts per second of how fast you open the throttle. A low v/s is easing on the gas...A high v/s is slamming the pedal to the floor. MS will avarage your settings I run dual 65mm throttle bodies my lowest is 0.6v/s my highest is 5.0v/s. With my dual TB's it does not take much movement of the tps to send mucho air inside so I've set all 4 bins fairly low to compensate. With my set up, I can't seem to get to high a v/s on the realtime display unless I SLAM my foot down into the floor board. The lower you set the v/s, you will also need to lower the fuel ammount in that bin also of you will go too rich. Good luck!
