Exhaust Still Popping After A Dyno

Exhaust Still Popping After A Dyno
2009 HD Night Train with a stage 1 (Screaming Eagle Race Tuner, Screaming Eagle High Air Flow Kit, Vance & Hines Big Radius 2 into 2 with Big City Thunder Baffles).
Prior to having a dyno done, exhaust was popping some when I would roll off the throttle and not pull the clutch in on decel. After a dyno, the exhaust is popping more on decel. I'm going back to the place I had the bike dynoed. Any thoughts on what I should tell them to modify.

Ask them if they know how to tune...

It has to do with the Tuning Tech actually DOING the WORK to get the VE's synchronized, identifying the timing requirements, and correcting the Accel/Decel changes....
Looking at your plugs is NOT how to tune an EFI bike... Back in the day it was the norm, but with the modern EFI System, coil/plug/wire combo, you end up with effecient combustion and gray to white plugs are the norm....
