Need a little help!! just installed a pcv, ais block offs from graves, Yoshi r77 slip on, bmc air filter and did the air box mod. The bike sounds killer by the way!!! But anyway it is real flat at anything under 5k rpms!? Dynojet does not have anything at all that is close to what I have as far as their map selection. The map that I currently have installed is for a two brothers slip on and stock air filter. Everything else in their map selection is for stock or European bikes!!!! Saw that a few people on here have about the same setup as me and are running the jumbo map. I would like to find this map if available. Also noticed a change in the shifting and throttle response. It now has smoother shifting and throttle but feels real flat down low. Thank you for your help.

i am getting a new stock airbox thursday to replace my modded box. i'm not really liking the way the bike sounds and feels with the AB mod.

EDIT:

Also the airbox mod seems to cause a loss of power in the lower RPM range.
