I have been getting some back firing latley on my 07 street glide. I have cobra long shots on it. anybody have any tips or thoughts on tuning settings?

 

get a pc 3 from fuel moto put one on and a world of difference

 

Get it dyno'ed, My daughter has one on her 2008 xl883c.&nbsp\\; It ran ok with the recommended settings.&nbsp\\; But she had it dyno'ed and the mid-range setting was too rich.
