Bigs, you should really get more info from our EFI members and/or research the forum for EFI threads.. I think there are variables involving catalyst's in the exhaust system, Lean stock EFI mapping, limited ability for stock EFI to compensate for induction/exhaust mods, etc etc... I guess I'm thinking there might be very little you should do without adding a EJK or PC-V for fueling management.. If Peabrain's bike is outfitted exactly as yours (catalyst, etc) then it would seem that the KDX snorkel will be ok.. BTW, I have a peabrain too..



If you want a performance boost you can actually feel, taste, and smell on every ride, you do the MCM (Marcelino Cam Mod) .. It takes a couple of hours - now that we know to just disable the KACR..
