Default 2016 883 with 1250 kit VE tables

So I have installed my 1250 kit and run multiple auto tunes. The bike feels great but has some decel popping. When I look at the VE tables there appears odd numbers in some of of the lower rpm/tps cells. See below - 1750/2, 1750/5, 2000/2 to name a few. Should I adjust these to be closer to the surrounding numbers

Are you using target tune or just the narrow bands?

Edit: sorry, I just noticed this wasnt a dynojet product. Is this the VH tuner?

Yea it’s a FP3. I rerun another tuning session and it’s better, but interesting the front VE table lowered some values and the rear increase some values.

That seems normal. You have a front and rear injector but with a common throttle body and manifold (not individual runners) there does appear to be "fuel stealing" between the cylinders.

So if I’m getting decel pop from 2500rpm down would I increase the VE table numbers in the 0 column in those ranges? And if so how much would you increase?

Will FP3 let you decrease or shut off "deceleration enleanment"? That's the better place to start. I'm not familiar enough with what tables FP3 gives you access to.

It has a table for deceleration enleanment and a table for acceleration enrichment. The enleanment table has a multiplier column which is editable, startin from 1.25 down to 1.00 at increasing temperature increments

I'm assuming you have an enleanment table with a column of numbers at temperatures and then a separate enleanment multipler table with single number. Make the single number enleanment multiplier table 0 (zero) and see if that helps.

Deceleration enleanment is purely an emissions thing and not desirable. A "zero" multiplier will disable it.
