Default AutoTune Make More Decel Popping...Possible?

Has anyone ever experienced an auto tune on a canned map make the bike run worse (more decel popping) or am I losing my mind??

I have an 07 XL1200R, V&H Upsweep 2into1 and Hammer Impact Air cleaner running a Power Vision. This exhaust has been a pain in the but to get the right tune.

I have sent my tune in to look at and am curious to anyone's thoughts while I wait...

This is from the Dynojet FAQ page

DECELERATION OR SHIFT POPPING
To address decel or shift popping, use the built in Power Vision feature Quick Tune. Start by adding fuel (+5), and spark (+3) in the decel columns, and then test. Adjust further if needed.

I did this and it didn't stop it completely but greatly reduced it.

Garbage in, garbage out. There is more to tuning than auto programs. A lot of things can spoil sampling during decel.

What kind of popping are you getting. A lot of little pops or one big pop?

It is a lot of little pops...I just received the revised remap from Fuel Moto and going to give it a try.

A little more info - After doing a little more research...other owners of this exhaust (V&H 2into1 Upsweep) had issues but have FP3s and V&H was finally able to provide them with a good map which fixed the issues. Thus, at least I know if they can fix it with an FP3, it will get resolved eventually with a PowerVision.

I am keeping my fingers crossed this revised tune works and will post back.
