Hey guys..
Lookin for a little help hear. Trying to get my head wrapped around this whole tuning thing.. Wow.. Tons of info.. I've read just about every post on this thread.. Here's where I am at.. I ride a 12 street bob.. 96, big sucker intake, bassani road rage 2/1, PV.. Just recently did my first auto tune and have taken pictures of the results for you all to take a look at for me and to see where I need to make changes.. Bike runs pretty good.. A little hot at times, and I have some decel popping.. More than I was expecting. Below are some charts to look at. Thanks in advance!
I really appreciate any feedback.. This is an area I am having a hard time at.. Thanks again

I found that increasing timing in the left column of you timing charts was a really easy method for getting rid of decel pop. Try adding a few degrees of timing to the decel/off throttle area and see how it does.

So I should add a few degrees to each line on the deceleration chart?

On your timing tables add a few degrees to the column on the left. It should be the 20 kpa column, might be 15 kpa. The only time you see these areas while riding is when you are decelerating.

Well adjusted the 20kpa chart for decel pop like Uncle Chester recommended.. Rode about 150 miles today, and all I can say is Wow! Not only did I barely have any decel pop, but my bike ran so good! It's almost like I felt more power and better throttle response.. Overall my bike was running top notch today.. Alot more to learn with that tuner, but I must say that from what I've read and gathered the last couple of days, reall has helped me have more of an understanding. Thanks all!

I notice the 2014 FLHX now has 2 molex connectors on the left side, which one is the data port to plug the PV into?
Edit,
sorry, just realized i have to buy the PV2 cable, guess I'm jumping the gun trying to get a new tune license from Dynojet.

1) How much the VE's are changing.
2) What cells were changed.
By looking at the VE table you posted neither 1 or 2 can be identified. So nothing to be learned or analyzed. Need to know how much change is happening and where the change is happening to really know if you need more work with the VE's or not. So leave timing alone and post your last VE delta. Do that and we can see what's going on.

Just wanted to say thanks to Crazylegs and JeffKill for posting their AFR and Spark Tables. I have been chasing down decel pop for quite awhile and today I modified my AFR table looking at your 2 AFR tables(had already modified my Spark tables earlier using JeffKills') anyway went for a ride and hardly a peep of decel pop, even did a hard accel from 0 to 80 and it sounded better than ever when shifting.
My modified AFR Table, most changes were to the 20 and 27 MAP columns:
