Anyone have any good experience using these? I just installed them on a streetbob but really couldnt tell much of a difference. Im running stock a/c with short shots. Hoping they would help with decel pop but no luck.

 

What settings have you tried? Short pipes are difficult to tune and you may have to go to something more versatile for tuning.

 

Ive tried 0 to100% with no luck. The nightrider instructions say 06 dyna 12% max while the 07 and later models say 75% max. I asked dk and they gave me a broad answer. Is there a difference with the efi system from 06 to 07?
