yellow 06

i have a 2006 shee that was all stock i ride on sea level .(i dont have much knowledge about banshees and im open to learn and tips) _ i just got dmc 916 v force 4 reeds and a moose boost bottle and dyno jet stage 3 - as i read the instalation manual with the reeds it said i had to cut the stock mount to allow instaling , i did as instructed .i mounted the exhaus correctly i also did what was told in the reed manual an installed them , i also put in the 270 main jets and but my needle is stock in . the boost bottle was also instaled . i tested the bike it was not perfect so i removed the reeds and put my stock ones in . the bike was working better but still not perfect . any ideas ? could it be the stock needle ?
