I'd try advancing the timing on low maps / TPS at the rpms you are chopping the throttle at..
This occurs in the 2800-3000 range mostly where I usually shift. If I winde it up 3.5-4k and shift, no pop. If I low rpm shift around 2.5k, no pop also. I will give your thought a try if no luck with Enleanment settings...one thing at a time for me so can back off any changes. Thanks!

Most of the time when I find an immediate pop between shifts is due to poor sealing at the headpipe junction.
High performance (non-tapered) exhaust gaskets are very difficult to get to seal when using a 1 piece headpipe because the heads are not precisely clocked to the header when torqued. That, and the fact quality control for pipes is not very precise for some pipe.
Tapered gaskets, when carefully used, will seal and handle imprecise headpipe to head mounting variables.
By altering the decel enleanment by at least 50% in either direction will give you feedback as how the table affects the between shift pops. Usually these pops are due to lean, not rich conditions.
Let us know what you find.

Will do thanks Bob. Im using stock head pipe that is decatt with stock conical type gaskets. Pipe has been off in the past and have verified all connections as tight and leak free. When I get a chance to ride when weather improves again, I will try going richer than lean if no change with symptoms.
Finally a good stretch of weather to do some trial and error and problem resolved. I started with going to a higher number which leans out the mixture in this transition phase..a bit better but nothing much. I then started decreasing the numbers (couple tenths) as temp rises, richening the mixture. Got slightly worse. So then I started halving the numbers as temp rises and got much better. Did another halving and now gone. Below is my starting table and current table. Thank you to all that responded, I hope it helps someone else with the new fp3 tuning. A users guide with helpful tips would be nice from V & H but other than that its been a good device.
I know this is an old thread, but I was having the same problem. I changed the deacceleration eleanment settings to what you have. How was your gas mileage after you changed the table. Did notice any ill effects making the change?
I abandoned this setup/tune after V&H released updated tunes for other makers pipes on the FP3. Once I used the specific setup that matched mine, my bike runs better than ever, no longer pings and never pops between shifts. My mpg on my last long ride was 45 which is up a couple points.

Good Morning Greg,
Thanks for the reply. Unfortunately, my map isn't available for the TAB Perfornabce 4.5 with Zombie baffles. I'm also running S&S Power Tune Duals which is similiar to V&H Power Duals. Bike is a 2016 RGS 103. I worked with V&H Customer Support and they gave me a new map which works really well, but i do get the occassional upshift pop as you describe.
Last night, I tried using your values in my Decel Enleanment table and it worked out pretty well. I was wondering how long you were running with these new values and if you noticed any issues after making the changes? did you pipes exhibit exessive sut from running richer, did you notice gas mileage going down? etc...

I ran those values in my tune over a year. I noticed no change in mpg before or after the change but that also was not a goal as I was doing well at about 41 on long rides. Around town was low 30s
