Got a 08 FXDF with Big Radius 2-1-big sucker and Sert.&nbsp\\; Have tried to lean it,richen it etc. and still have a nasty decel pop that I cannot get rid of. I even changed the exhaust gaskets to make sure they were not leaking.&nbsp\\; Anyone else with this pipe got this problem?&nbsp\\; Thanks

 

What gears are you testing the pop in and what RMP is the popping happening and where are you adding fuel and what tuning table are you using....lots of ands huh?

 

Pop happens in all gears at 3,000 rpms and up and even just free revving.&nbsp\\; I have added and removed fuel front the decel enleanment and it always acts the same. seems to be too rich as I get a big blue flame out of the pipe.&nbsp\\; I am going to try to remove some fuel from the VE tables at 0% throttle and see what happens.&nbsp\\; Dunno?

 

Sounds as if your base map is too rich....take out some VE like you said and let us know how much VE had to be removed to get the blue flame out .

 

Will do!
Thanks!
