New pipes and silencer....sluggish on the bottom end

[tallcoolone]

I have an 02 banshee with pro circuit platinum pipes and 304 silencers. I have added a boost bottle and she is sluggish until about half throttle then she opens up and screams. I have been told to use a dyno jet kit and that should take care of the problem. Does anyone have any experience with this?

get rid of the boost bottle, and ditch the dynojet main jets if they are not mikuni. You probably need to adjust the needle clip position. Those fucking bottles are junk.
